<para>This parameter has a structured value. It is a table of space-delimited
path/value pairs. Each path identifies some element in the source document
using a restricted subset of XPath (only the implicit child axis, no wildcards,
no predicates). Paths can be either relative or absolute.</para>

<para>When processing a particular element, the stylesheets consult this table to
determine if a ToC (or LoT(s)) should be generated.</para>

<para>For example, consider the entry:</para>

<screen>book toc,figure</screen>

<para>This indicates that whenever a <tag>book</tag> is formatted, a
Table Of Contents and a List of Figures should be generated. Similarly,</para>

<screen>/chapter toc</screen>

<para>indicates that whenever a document <emphasis>that has a root
of</emphasis> <tag>chapter</tag> is formatted, a Table of
Contents should be generated. The entry <literal>chapter</literal> would match
all chapters, but <literal>/chapter</literal> matches only <tag>chapter</tag>
document elements.</para>

<para>Generally, the longest match wins. So, for example, if you want to distinguish
articles in books from articles in parts, you could use these two entries:</para>

<screen>book/article toc,figure
part/article toc</screen>

<para>Note that an article in a part can never match a <literal>book/article</literal>,
so if you want nothing to be generated for articles in parts, you can simply leave
that rule out.</para>

<para>If you want to leave the rule in, to make it explicit that you're turning
something off, use the value <quote>nop</quote>. For example, the following
entry disables ToCs and LoTs for articles:</para>

<screen>article nop</screen>

<para>Do not simply leave the word <quote>article</quote> in the file
without a matching value. That'd be just begging the silly little
path/value parser to get confused.</para>

<para>Section ToCs are further controlled by the
<parameter>generate.section.toc.level</parameter> parameter.
For a given section level to have a ToC, it must have both an entry in 
<parameter>generate.toc</parameter> and be within the range enabled by
<parameter>generate.section.toc.level</parameter>.</para>

<para>This parameter lets you select which method to use for sorting and grouping
 index entries in an index.
Indexes in Latin-based languages that have accented characters typically
sort together accented words and unaccented words.
Thus <quote>&#193;</quote> (U+00C1 LATIN CAPITAL LETTER A WITH ACUTE) would sort together
with <quote>A</quote> (U+0041 LATIN CAPITAL LETTER A), so both would appear in the <quote>A</quote>
section of the index.
Languages using other alphabets (such as Russian,  which is written in the Cyrillic alphabet)
and languages using ideographic chararacters (such as Japanese)
require grouping specific to the languages and alphabets.
</para>

<para>The default indexing method is limited.
It can group accented characters in Latin-based languages only.
It cannot handle non-Latin alphabets or ideographic languages.
The other indexing methods require extensions of one type or
another, and do not work with
all XSLT processors, which is why they are not used by default.</para>

<para>The three choices for indexing method are:</para>
<variablelist>
<varlistentry>
<term><literal>basic</literal></term>
<listitem>
<para>
(default)  Sort and groups words based only on the Latin alphabet.
Words with accented Latin letters will group and sort with
their respective primary letter, but
words in non-Latin alphabets will be
put in the <quote>Symbols</quote> section of the index.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><literal>kosek</literal></term>
<listitem>
<para>
This method sorts and groups words based on letter groups configured in
the DocBook locale file for the given language.
See, for example, the French locale file <filename>common/fr.xml</filename>.
This method requires that the XSLT processor
supports the EXSLT extensions (most do).
It also requires support for using 
user-defined functions in xsl:key (xsltproc does not).
</para>
<para>This method is suitable for any language for which you can
list all the individual characters that should appear
in each letter group in an index.
It is probably not practical to use it for ideographic languages
such as Chinese that have hundreds or thousands of characters.
</para>

<para>To use the kosek method, you must:</para>

<orderedlist>
<listitem>
<para>Use a processor that supports its extensions, such as
Saxon 6 or Xalan (xsltproc and Saxon 8 do not).
</para>
</listitem>
<listitem>
<para>Set the index.method parameter's value to <quote>kosek</quote>.
</para>
</listitem>

<term><literal>kimber</literal></term>
<listitem>
<para>
This method uses extensions to the Saxon processor to implement
sophisticated indexing processes. It uses its own 
configuration file, which can include information for any number of
languages. Each language's configuration can group
words using one of two processes. In the
enumerated process similar to that used in the kosek method,
you indicate the groupings character-by-character.
In the between-key process, you specify the
break-points in the sort order that should start a new group.
The latter configuration is useful for ideographic languages
such as Chinese, Japanese, and Korean.
You can also define your own collation algorithms and how you
want mixed Latin-alphabet words sorted.</para>

<para>The default value is 1, so index entries link to

<para>When set to 0, an index entry takes you 
to the precise location of its corresponding indexterm.
However, if you have a lot of duplicate
entries in sections, then you have a lot of duplicate
titles in the index, which makes it more cluttered.
The reader may not recognize why duplicate titles
appear until they follow the links. Also, the links
may land the reader in the middle of a section where the
section title is not visible, which may also be
confusing to the reader.</para>

<listitem>
<para>When set to 1, an index entry link is
less precise, but duplicate titles in the

not a location within the section.

<para>If non-zero, number labels for <tag>chapter</tag>,
<tag>appendix</tag>, and other component elements are prefixed with
the label of the part element that contains them.  So you might see
Chapter II.3 instead of Chapter 3.  Also, the labels for formal
elements such as <tag>table</tag> and <tag>figure</tag> will include
the part label.  If there is no part element container, then no prefix
is generated.
</para>
<para>
This feature is most useful when the
<parameter>label.from.part</parameter> parameter is turned on.
In that case, there would be more than one <tag>chapter</tag>
<quote>1</quote>, and the extra part label prefix will identify
each chapter unambiguously.

<para>The <parameter>docbook.css.source</parameter> parameter
specifies the name of the file containing the default DocBook
CSS styles.  Those styles are necessary when the
<parameter>make.clean.html</parameter> parameter is nonzero.</para>

<para>The file is a well-formed XML file that
must consist of a single <tag>style</tag> root
element that contains CSS styles as its text content.
The default value of the parameter (and filename)
is <literal>docbook.css.xml</literal>.
The stylesheets ship with the default file. You can substitute
your own and specify its path in this parameter.</para>

<para>If <parameter>docbook.css.source</parameter> is not blank,
and <parameter>make.clean.html</parameter> is nonzero, then
the stylesheet takes the following actions:</para>

<orderedlist>
  <listitem>
    <para>The stylesheet uses the XSLT <literal>document()</literal>
    function to open the file specified by the parameter and
    load it into a variable.</para>
  </listitem>
  <listitem>
    <para>The stylesheet forms an output pathname consisting of the
    value of the <parameter>base.dir</parameter> parameter (if it is set)
    and the value of <parameter>docbook.css.source</parameter>,
    with the <literal>.xml</literal> suffix stripped off.
    </para>
  </listitem>
  <listitem>
    <para>The stylesheet removes the <tag>style</tag>
    wrapper element and writes just the CSS text content to the output file.</para>
  </listitem>
  <listitem>
    <para>The stylesheet adds a <tag>link</tag> element to the
    HTML <tag>HEAD</tag> element to reference the external CSS stylesheet.
    For example:</para>
    <programlisting>&lt;link rel="stylesheet" href="docbook.css" type="text/css"&gt;
    </programlisting>
    <para>However, if the <parameter>docbook.css.link</parameter>
    parameter is set to zero, then no <tag>link</tag> is written
    for the default CSS file.  That is useful if a custom
    CSS file will import the default CSS stylesheet to ensure
    proper cascading of styles.</para>
  </listitem>
</orderedlist>

<para>If the <parameter>docbook.css.source</parameter> parameter
is changed from its default <literal>docbook.css.xml</literal> to blank,
then no default CSS is generated. Likewise if the
<parameter>make.clean.html</parameter> parameter is set to zero,
then no default CSS is generated. The 
<parameter>custom.css.source</parameter> parameter can be used

<para>The stylesheets are capable of generating a default
CSS stylesheet file.  The parameters 
<parameter>make.clean.html</parameter> and
<parameter>docbook.css.source</parameter> control that feature.</para>

<para>Normally if a default CSS file is generated, then 
the stylesheet inserts a <tag>link</tag> tag in the HTML
<tag>HEAD</tag> element to reference it.
However, you can omit that <tag>link</tag> reference if
you set the <parameter>docbook.css.link</parameter> to zero
(1 is the default).</para>

<para>This parameter is useful when you want to import the 
default CSS into a custom CSS file generated using the
<parameter>custom.css.source</parameter> parameter.

  <refsection><info><title>Description</title></info>

<para>The <parameter>custom.css.source</parameter>
parameter enables you to add CSS styles to DocBook's
HTML output.</para>

<para>The parameter
specifies the name of a file containing custom
CSS styles.  The file must be a well-formed XML file that
consists of a single <tag>style</tag> root
element that contains CSS styles as its text content.
For example:</para>
<programlisting>&lt;?xml version="1.0"?&gt;
&lt;style&gt;
h2 {
  font-weight: bold;
  color: blue;
}
...
&lt;/style&gt;
</programlisting>

<para>The filename specified by the parameter
should have a <literal>.xml</literal>
filename suffix, although that is not required.
The default value of this parameter is blank.</para>

<para>If <parameter>custom.css.source</parameter> is not blank, then
the stylesheet takes the following actions.
These actions take place regardless of the value of
the <parameter>make.clean.html</parameter> parameter.</para>

<orderedlist>
  <listitem>
    <para>The stylesheet uses the XSLT <literal>document()</literal>
    function to open the file specified by the parameter and
    load it into a variable.</para>
  </listitem>
  <listitem>
    <para>The stylesheet forms an output pathname consisting of the
    value of the <parameter>base.dir</parameter> parameter (if it is set)
    and the value of <parameter>custom.css.source</parameter>,
    with the <literal>.xml</literal> suffix stripped off.
    </para>
  </listitem>
  <listitem>
    <para>The stylesheet removes the <tag>style</tag>
    wrapper element and writes just the CSS text content to the output file.</para>
  </listitem>
  <listitem>
    <para>The stylesheet adds a <tag>link</tag> element to the
    HTML <tag>HEAD</tag> element to reference this external CSS stylesheet.
    For example:
    <programlisting>&lt;link rel="stylesheet" href="custom.css" type="text/css"&gt;
    </programlisting>
    </para>
  </listitem>
</orderedlist>



<para>If the <parameter>make.clean.html</parameter> parameter is nonzero
(the default is zero),
and if the <parameter>docbook.css.source</parameter> parameter
is not blank (the default is not blank),
then the stylesheet will also generate a default CSS file
and add a <tag>link</tag> tag to reference it.
The <tag>link</tag> to the custom CSS comes after the 
<tag>link</tag> to the default, so it should cascade properly
in most browsers.
If you do not want two <tag>link</tag> tags, and
instead want your custom CSS to import the default generated
CSS file, then do the following:
</para>

<orderedlist>
  <listitem>
    <para>Add a line like the following to your custom CSS source file:</para>
    <programlisting>@import url("docbook.css")
    </programlisting>
  </listitem>
  <listitem>
    <para>Set the <parameter>docbook.css.link</parameter> parameter 
    to zero. This will omit the <tag>link</tag> tag
    that references the default CSS file.</para>
  </listitem>
</orderedlist>

<para>If you set <parameter>make.clean.html</parameter> to nonzero but
you do not want the default CSS generated, then also set
the <parameter>docbook.css.source</parameter> parameter to blank.
Then no default CSS will be generated, and so
all CSS styles must come from your custom CSS file.</para>

<para>You can use the <parameter>generate.css.header</parameter>
parameter to instead write the CSS to each HTML <tag>HEAD</tag>
element in a <tag>style</tag> tag instead of an external CSS file.</para>

<parameter>custom.css.source</parameter> control that feature.</para>

<para>If you require that CSS styles reside in the HTML 
<tag>HEAD</tag> element instead of external CSS files,
then set the <parameter>generate.css.header</parameter>
parameter to nonzero (it is zero by default).
Then instead of generating the CSS in external files,
they are wrapped in <tag>style</tag> elements in
the <tag>HEAD</tag> element of each HTML output file.

<parameter>html.head.legalnotice.link.types</parameter> is a
space-separated list of link types, as described in <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.w3.org/TR/html401/types.html#type-links">Section 6.12
of the HTML 4.01 specification</link>. If the value of the
<parameter>generate.legalnotice.link</parameter> parameter is
non-zero, then the stylesheet generates (in the
<literal>head</literal> section of the HTML source) either a single
HTML <literal>link</literal> element or, if the value of the
<parameter>html.head.legalnotice.link.multiple</parameter> is
non-zero, one <literal>link</literal> element for each link type
specified. Each <literal>link</literal> has the following attributes:

<itemizedlist>
  <listitem>
    <para>a <tag class="attribute">rel</tag> attribute whose
    value is derived from the value of
    <parameter>html.head.legalnotice.link.types</parameter></para>
  </listitem>
  <listitem>
    <para>an <tag class="attribute">href</tag> attribute whose
    value is set to the URL of the file containing the
    <tag>legalnotice</tag></para>
  </listitem>
  <listitem>
    <para>a <tag class="attribute">title</tag> attribute whose
    value is set to the title of the corresponding
    <tag>legalnotice</tag> (or a title programatically
    determined by the stylesheet)</para>
  </listitem>
</itemizedlist>

For example:

<screen>  &lt;link rel="license" href="ln-id2524073.html" title="Legal Notice"&gt;</screen>
</para>

<refsection><info><title>About the default value</title></info>
  
  <para>In an ideal world, the default value of
  <parameter>html.head.legalnotice.link.types</parameter> would
  probably be &#8220;<literal>license</literal>&#8221;, since the content of the
  DocBook <tag>legalnotice</tag> is typically license
  information, not copyright information. However, the default value
  is &#8220;<literal>copyright</literal>&#8221; for pragmatic reasons: because
  that&#8217;s among the set of &#8220;recognized link types&#8221; listed in <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.w3.org/TR/html401/types.html#type-links">Section
  6.12 of the HTML 4.01 specification</link>, and because certain
  browsers and browser extensions are preconfigured to recognize that
  value.</para>

<para>If <parameter>html.head.legalnotice.link.multiple</parameter> is
non-zero and the value of
<parameter>html.head.legalnotice.link.types</parameter> contains
multiple link types, then the stylesheet generates (in the
<literal>head</literal> section of the HTML source) one
<literal>link</literal> element for each link type specified. For
example, if the value of
<parameter>html.head.legalnotice.link.types</parameter> is
&#8220;<literal>copyright license</literal>&#8221;:

<screen>  &lt;link rel="copyright" href="ln-id2524073.html" title="Legal Notice"&gt;
  &lt;link rel="license" href="ln-id2524073.html" title="Legal Notice"&gt;</screen>

 Otherwise, the stylesheet generates generates a single
 <literal>link</literal> instance; for example:

<screen>  &lt;link rel="copyright license" href="ln-id2524073.html" title="Legal Notice"&gt;</screen>

<para>When cross reference data is collected for resolving olinks, it
may be necessary to prepend a base URI to each target's href. This
parameter lets you set that base URI when cross reference data is
collected. This feature is needed when you want to link to a document
that is processed without chunking. The output filename for such a
document is not known to the XSL stylesheet; the only target
information consists of fragment identifiers such as
<literal>#idref</literal>. To enable the resolution of olinks between
documents, you should pass the name of the HTML output file as the
value of this parameter. Then the hrefs recorded in the cross
reference data collection look like
<literal>outfile.html#idref</literal>, which can be reached as links
from other documents.</para>

<para>When cross reference data is collected for use by olinks, the data for each potential target includes one field containing a completely assembled cross reference string, as if it were an xref generated in that document. Other fields record the separate title, number, and element name of each target. When an olink is formed to a target from another document, the olink resolves to that preassembled string by default. If the <parameter>use.local.olink.style</parameter> parameter is set to non-zero, then instead the cross
reference string is formed again from the target title, number, and
element name, using the stylesheet processing the targeting document.
Then olinks will match the xref style in the targeting document
rather than in the target document. If  both documents are processed
with the same stylesheet, then the results will be the same.</para>

<para>When olinks between documents are resolved for HTML output, the stylesheet can compute the relative path between the current document and the target document. The stylesheet needs to know the <literal>targetdoc</literal> identifiers for both documents, as they appear in the <parameter>target.database.document</parameter> database file. This parameter passes to the stylesheet
the targetdoc identifier of the current document, since that
identifier does not appear in the document itself. </para>
<para>This parameter can also be used for print output.

<para>When olinks between documents are resolved, the generated text
may not make it clear that the reference is to another document.
It is possible for the stylesheets to append the other document's
title to external olinks. For this to happen, two parameters must
be set.</para>
<itemizedlist>
<listitem>
<para>This <parameter>olink.doctitle</parameter> parameter
should be set to either <literal>yes</literal> or <literal>maybe</literal>
to enable this feature.

</listitem>
<listitem>
<para>And you should also set the <parameter>current.docid</parameter>
parameter to the document id for the  document currently
being processed for output.
</para>
</listitem>
</itemizedlist>

<para>
Then if an olink's  <literal>targetdoc</literal> id differs from
the <literal>current.docid</literal> value, the stylesheet knows
that it is a reference to another document and can
append the target document's
title to the generated olink text. </para> 

<para>The text for the target document's title is copied from the
olink database from the <tag>ttl</tag> element
of the top-level <tag>div</tag> for that document.
If that <tag>ttl</tag> element is missing or empty,
no title is output.

<para>This parameter defines a list of lang values
to search among to resolve olinks.
</para>

<para>Normally an olink tries to resolve to a document in the same
language as the olink itself.  The language of an olink
is determined by its nearest ancestor element with a
<tag class="attribute">lang</tag> attribute, otherwise the
value of the <parameter>l10n.gentext.default.lang</parameter>
parameter.
</para>

<para>An olink database can contain target data for the same
document in multiple languages.  Each set of data has the
same value for the <tag>targetdoc</tag> attribute in
the <tag>document</tag> element in the database, but with a 
different <tag>lang</tag> attribute value.
</para>

<para>When an olink is being resolved, the target is first
sought in the document with the same language as the olink.
If no match is found there, then this parameter is consulted
for additional languages to try.</para>

<para>The <parameter>olink.lang.fallback.sequence</parameter>
must be a whitespace separated list of lang values to
try.  The first one with a match in the olink database is used.
The default value is empty.</para>

<para>For example, a document might be written in German
and contain an olink with
<literal>targetdoc="adminguide"</literal>.
When the document is processed, the processor
first looks for a target dataset in the
olink database starting with:</para>

<literallayout><literal>&lt;document targetdoc="adminguide" lang="de"&gt;</literal>.
</literallayout>

<para>If there is no such element, then the
<parameter>olink.lang.fallback.sequence</parameter> 
parameter is consulted.
If its value is, for example, <quote>fr en</quote>, then the processor next
looks for <literal>targetdoc="adminguide" lang="fr"</literal>, and
then for <literal>targetdoc="adminguide" lang="en"</literal>.
If there is still no match, it looks for
<literal>targetdoc="adminguide"</literal> with no
lang attribute.
</para>

<para>This parameter is useful when a set of documents is only
partially translated, or is in the process of being translated.  
If a target of an olink has not yet been translated, then this
parameter permits the processor to look for the document in
other languages.  This assumes the reader would rather have
a link to a document in a different language than to have
a broken link.

<para>Olinks that point to targets within the same document

<para>Page number references for olinks to
external documents can only be inserted if the 
information exists in the olink database. 
This means each olink target element 
(<tag>div</tag> or <tag>obj</tag>)
must have a <tag class="attribute">page</tag> attribute
whose value is its page number in the target document.
The XSL stylesheets are not able to extract that information
during processing because pages have not yet been created in
XSLT transformation.  Only the XSL-FO processor knows what
page each element is placed on.
Therefore some postprocessing must take place to populate
page numbers in the olink database.

<para>The value of this parameter determines whether
the cross reference URIs to PDF documents made with
<tag>olink</tag> will 
include fragment identifiers.
</para>

<para>When forming a URI to link to a PDF document,
a fragment identifier (typically a '#' followed by an
id value) appended to the PDF filename can be used by
the PDF viewer to open
the PDF file to a location within the document instead of
the first page.
However, not all PDF files have id
values embedded in them, and not all PDF viewers can
handle fragment identifiers. 
</para>

<para>If <parameter>insert.olink.pdf.frag</parameter> is set
to a non-zero value, then any olink targeting a
PDF file will have the fragment identifier appended to the URI.
The URI is formed by concatenating the value of the
<parameter>olink.base.uri</parameter> parameter, the
value of the <tag class="attribute">baseuri</tag>
attribute from the <tag class="element">document</tag>
element in the olink database with the matching
<tag class="attribute">targetdoc</tag> value,
and the value of the <tag class="attribute">href</tag>
attribute for the targeted element in the olink database.
The <tag class="attribute">href</tag> attribute
contains the fragment identifier.
</para>

<para>If <parameter>insert.olink.pdf.frag</parameter> is set
to zero (the default value), then 
the <tag class="attribute">href</tag> attribute
from the olink database
is not appended to PDF olinks, so the fragment identifier is left off.
A PDF olink is any olink for which the
<tag class="attribute">baseuri</tag> attribute
from the matching <tag class="element">document</tag>
element in the olink database ends with '.pdf'.
Any other olinks will still have the fragment identifier added.

<para>If you are re-using XML content modules in multiple documents,
you may want to redirect some of your olinks.  This parameter
permits you to redirect an olink to the current document.
</para>

<para>For example: you are writing documentation for a  product, 
which includes 3 manuals: a little installation
booklet (booklet.xml), a user 
guide (user.xml), and a reference manual (reference.xml).
All 3 documents begin with the same introduction section (intro.xml) that 
contains a reference to the customization section (custom.xml) which is 
included in both user.xml and reference.xml documents.
</para>

<para>How do you write the link to custom.xml in intro.xml
so that it is interpreted correctly in all 3 documents?</para>
<itemizedlist>
<listitem><para>If you use xref, it will fail in user.xml.</para>
</listitem>
<listitem><para>If you use olink (pointing to reference.xml),
the reference in user.xml  
will point to the customization section of the reference manual, while it is 
actually available in user.xml.</para>
</listitem>
</itemizedlist>

<para>If you set the <parameter>prefer.internal.olink</parameter>
parameter to a non-zero value, then the processor will
first look in the olink database
for the olink's <tag>targetptr</tag> attribute value
in document matching the <parameter>current.docid</parameter>
parameter value.  If it isn't found there, then
it tries the document in the database
with the <tag>targetdoc</tag>
value that matches the olink's <tag>targetdoc</tag>
attribute.
</para>

<para>This feature permits an olink reference to resolve to
the current document if there is an element
with an id matching the olink's <tag>targetptr</tag>
value.  The current document's olink data must be
included in the target database for this to work.</para>

<caution>
<para>There is a potential for incorrect links if
the same <tag>id</tag> attribute value is used for different
content in different documents.
Some of your olinks may be redirected to the current document
when they shouldn't be.  It is not possible to control
individual olink instances.</para>
</caution>

<para>
In order to resolve olinks efficiently, the stylesheets can
generate an external data file containing information about
all potential cross reference endpoints in a document.
This parameter determines whether the collection process is run when the document is processed by the stylesheet. The default value is  <literal>no</literal>, which means the data file is not generated during processing. The other choices are <literal>yes</literal>, which means the data file is created and the document is processed for output, and <literal>only</literal>, which means the data file is created but the document is not processed for output.

<para>Maintaining bibliography entries across a set of documents is tedious, time
consuming, and error prone. It makes much more sense, usually, to store all of
the bibliography entries in a single place and simply <quote>extract</quote>
the ones you need in each document.</para>

<para>That's the purpose of the
<parameter>bibliography.collection</parameter> parameter. To setup a global
bibliography <quote>database</quote>, follow these steps:</para>

<para>First, create a stand-alone bibliography document that contains all of
the documents that you wish to reference. Make sure that each bibliography
entry (whether you use <tag>biblioentry</tag> or <tag>bibliomixed</tag>)
has an ID.</para>

<para>My global bibliography, <filename>~/bibliography.xml</filename> begins
like this:</para>

<informalexample>
<programlisting>&lt;!DOCTYPE bibliography
  PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
  "http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"&gt;
&lt;bibliography&gt;&lt;title&gt;References&lt;/title&gt;

&lt;bibliomixed id="xml-rec"&gt;&lt;abbrev&gt;XML 1.0&lt;/abbrev&gt;Tim Bray,
Jean Paoli, C. M. Sperberg-McQueen, and Eve Maler, editors.
&lt;citetitle&gt;&lt;ulink url="http://www.w3.org/TR/REC-xml"&gt;Extensible Markup

&lt;/bibliomixed&gt;

&lt;bibliomixed id="xml-names"&gt;&lt;abbrev&gt;Namespaces&lt;/abbrev&gt;Tim Bray,
Dave Hollander,
and Andrew Layman, editors.

XML&lt;/ulink&gt;&lt;/citetitle&gt;.
World Wide Web Consortium, 1999.
&lt;/bibliomixed&gt;

&lt;!-- ... --&gt;
&lt;/bibliography&gt;
</programlisting>
</informalexample>

<para>When you create a bibliography in your document, simply
provide <emphasis>empty</emphasis> <tag>bibliomixed</tag>
entries for each document that you wish to cite. Make sure that these
elements have the same ID as the corresponding <quote>real</quote>
entry in your global bibliography.</para>

<para>For example:</para>

<informalexample>
<programlisting>&lt;bibliography&gt;&lt;title&gt;Bibliography&lt;/title&gt;

&lt;bibliomixed id="xml-rec"/&gt;
&lt;bibliomixed id="xml-names"/&gt;
&lt;bibliomixed id="DKnuth86"&gt;Donald E. Knuth. &lt;citetitle&gt;Computers and
Typesetting: Volume B, TeX: The Program&lt;/citetitle&gt;. Addison-Wesley,
1986.  ISBN 0-201-13437-3.
&lt;/bibliomixed&gt;
&lt;bibliomixed id="relaxng"/&gt;

&lt;/bibliography&gt;</programlisting>
</informalexample>

<para>Note that it's perfectly acceptable to mix entries from your
global bibliography with <quote>normal</quote> entries. You can use
<tag>xref</tag> or other elements to cross-reference your
bibliography entries in exactly the same way you do now.</para>

<para>Finally, when you are ready to format your document, simply set the
<parameter>bibliography.collection</parameter> parameter (in either a
customization layer or directly through your processor's interface) to
point to your global bibliography.</para>

<para>The stylesheets will format the bibliography in your document as if
all of the entries referenced appeared there literally.</para>

<para>Glossaries maintained independently across a set of documents
are likely to become inconsistent unless considerable effort is
expended to keep them in sync. It makes much more sense, usually, to
store all of the glossary entries in a single place and simply
<quote>extract</quote> the ones you need in each document.</para>

<para>That's the purpose of the
<parameter>glossary.collection</parameter> parameter. To setup a global
glossary <quote>database</quote>, follow these steps:</para>

<refsection><info><title>Setting Up the Glossary Database</title></info>

<para>First, create a stand-alone glossary document that contains all of
the entries that you wish to reference. Make sure that each glossary
entry has an ID.</para>

<para>Here's an example glossary:</para>

<informalexample>
<programlisting>
&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;!DOCTYPE glossary
  PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
  "http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"&gt;
&lt;glossary&gt;
&lt;glossaryinfo&gt;
&lt;editor&gt;&lt;firstname&gt;Eric&lt;/firstname&gt;&lt;surname&gt;Raymond&lt;/surname&gt;&lt;/editor&gt;
&lt;title&gt;Jargon File 4.2.3 (abridged)&lt;/title&gt;
&lt;releaseinfo&gt;Just some test data&lt;/releaseinfo&gt;
&lt;/glossaryinfo&gt;

&lt;glossdiv&gt;&lt;title&gt;0&lt;/title&gt;

&lt;glossentry&gt;
&lt;glossterm&gt;0&lt;/glossterm&gt;
&lt;glossdef&gt;
&lt;para&gt;Numeric zero, as opposed to the letter `O' (the 15th letter of
the English alphabet). In their unmodified forms they look a lot
alike, and various kluges invented to make them visually distinct have
compounded the confusion. If your zero is center-dotted and letter-O
is not, or if letter-O looks almost rectangular but zero looks more
like an American football stood on end (or the reverse), you're
probably looking at a modern character display (though the dotted zero
seems to have originated as an option on IBM 3270 controllers). If
your zero is slashed but letter-O is not, you're probably looking at
an old-style ASCII graphic set descended from the default typewheel on
the venerable ASR-33 Teletype (Scandinavians, for whom /O is a letter,
curse this arrangement). (Interestingly, the slashed zero long
predates computers; Florian Cajori's monumental "A History of
Mathematical Notations" notes that it was used in the twelfth and
thirteenth centuries.) If letter-O has a slash across it and the zero
does not, your display is tuned for a very old convention used at IBM
and a few other early mainframe makers (Scandinavians curse &lt;emphasis&gt;this&lt;/emphasis&gt;
arrangement even more, because it means two of their letters collide).
Some Burroughs/Unisys equipment displays a zero with a &lt;emphasis&gt;reversed&lt;/emphasis&gt;
slash. Old CDC computers rendered letter O as an unbroken oval and 0
as an oval broken at upper right and lower left. And yet another
convention common on early line printers left zero unornamented but
added a tail or hook to the letter-O so that it resembled an inverted
Q or cursive capital letter-O (this was endorsed by a draft ANSI
standard for how to draw ASCII characters, but the final standard
changed the distinguisher to a tick-mark in the upper-left corner).
Are we sufficiently confused yet?&lt;/para&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;

&lt;glossentry&gt;
&lt;glossterm&gt;1TBS&lt;/glossterm&gt;
&lt;glossdef&gt;
&lt;para role="accidence"&gt;
&lt;phrase role="pronounce"&gt;&lt;/phrase&gt;
&lt;phrase role="partsofspeach"&gt;n&lt;/phrase&gt;
&lt;/para&gt;
&lt;para&gt;The "One True Brace Style"&lt;/para&gt;
&lt;glossseealso&gt;indent style&lt;/glossseealso&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;

&lt;/glossdiv&gt;

&lt;!-- ... --&gt;

&lt;/glossary&gt;</programlisting>

</refsection>

<refsection><info><title>Marking Up Glossary Terms</title></info>

<para>That takes care of the glossary database, now you have to get the entries
into your document. Unlike bibliography entries, which can be empty, creating
<quote>placeholder</quote> glossary entries would be very tedious. So instead,
support for <parameter>glossary.collection</parameter> relies on implicit linking.</para>

<para>In your source document, simply use <tag>firstterm</tag> and
<tag>glossterm</tag> to identify the terms you wish to have included
in the glossary. The stylesheets assume that you will either set the
<tag class="attribute">baseform</tag> attribute correctly, or that the
content of the element exactly matches a term in your glossary.</para>

<para>If you're using a <parameter>glossary.collection</parameter>, don't
make explicit links on the terms in your document.</para>

<para>So, in your document, you might write things like this:</para>

<informalexample>
<programlisting>&lt;para&gt;This is dummy text, without any real meaning.
The point is simply to reference glossary terms like &lt;glossterm&gt;0&lt;/glossterm&gt;
and the &lt;firstterm baseform="1TBS"&gt;One True Brace Style (1TBS)&lt;/firstterm&gt;.
The &lt;glossterm&gt;1TBS&lt;/glossterm&gt;, as you can probably imagine, is a nearly
religious issue.&lt;/para&gt;</programlisting>
</informalexample>

<para>If you set the <parameter>firstterm.only.link</parameter> parameter,
only the terms marked with <tag>firstterm</tag> will be links.
Otherwise, all the terms will be linked.</para>

</refsection>

<refsection><info><title>Marking Up the Glossary</title></info>

<para>The glossary itself has to be identified for the stylesheets. For lack
of a better choice, the <tag class="attribute">role</tag> is used.
To identify the glossary as the target for automatic processing, set
the role to <quote><literal>auto</literal></quote>. The title of this
glossary (and any other information from the <tag>glossaryinfo</tag>
that's rendered by your stylesheet) will be displayed, but the entries will
come from the database.
</para>

<para>Unfortunately, the glossary can't be empty, so you must put in
at least one <tag>glossentry</tag>. The content of this entry
is irrelevant, it will not be rendered:</para>

<informalexample>
<programlisting>&lt;glossary role="auto"&gt;
&lt;glossentry&gt;
&lt;glossterm&gt;Irrelevant&lt;/glossterm&gt;
&lt;glossdef&gt;
&lt;para&gt;If you can see this, the document was processed incorrectly. Use
the &lt;parameter&gt;glossary.collection&lt;/parameter&gt; parameter.&lt;/para&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;
&lt;/glossary&gt;</programlisting>
</informalexample>

<para>What about glossary divisions? If your glossary database has glossary
divisions <emphasis>and</emphasis> your automatic glossary contains at least
one <tag>glossdiv</tag>, the automic glossary will have divisions.
If the <tag>glossdiv</tag> is missing from either location, no divisions
will be rendered.</para>

<para>Glossary entries (and divisions, if appropriate) in the glossary will
occur in precisely the order they occur in your database.</para>

</refsection>

<refsection><info><title>Formatting the Document</title></info>

<para>Finally, when you are ready to format your document, simply set the
<parameter>glossary.collection</parameter> parameter (in either a
customization layer or directly through your processor's interface) to
point to your global glossary.</para>

<para>The stylesheets will format the glossary in your document as if
all of the entries implicilty referenced appeared there literally.</para>
</refsection>

<refsection><info><title>Limitations</title></info>

<para>Glossary cross-references <emphasis>within the glossary</emphasis> are
not supported. For example, this <emphasis>will not</emphasis> work:</para>

<informalexample>
<programlisting>&lt;glossentry&gt;
&lt;glossterm&gt;gloss-1&lt;/glossterm&gt;
&lt;glossdef&gt;&lt;para&gt;A description that references &lt;glossterm&gt;gloss-2&lt;/glossterm&gt;.&lt;/para&gt;
&lt;glossseealso&gt;gloss-2&lt;/glossseealso&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;</programlisting>
</informalexample>

<para>If you put glossary cross-references in your glossary that way,
you'll get the cryptic error: <computeroutput>Warning:
glossary.collection specified, but there are 0 automatic
glossaries</computeroutput>.</para>

<para>Instead, you must do two things:</para>

<orderedlist>
<listitem>
<para>Markup your glossary using <tag>glossseealso</tag>:</para>

<informalexample>
<programlisting>&lt;glossentry&gt;
&lt;glossterm&gt;gloss-1&lt;/glossterm&gt;
&lt;glossdef&gt;&lt;para&gt;A description that references &lt;glossterm&gt;gloss-2&lt;/glossterm&gt;.&lt;/para&gt;
&lt;glossseealso&gt;gloss-2&lt;/glossseealso&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;</programlisting>
</informalexample>
</listitem>

<listitem>
<para>Make sure there is at least one <tag>glossterm</tag> reference to
<glossterm>gloss-2</glossterm> <emphasis>in your document</emphasis>. The
easiest way to do that is probably within a <tag>remark</tag> in your
automatic glossary:</para>

<informalexample>
<programlisting>&lt;glossary role="auto"&gt;
&lt;remark&gt;Make sure there's a reference to &lt;glossterm&gt;gloss-2&lt;/glossterm&gt;.&lt;/remark&gt;
&lt;glossentry&gt;
&lt;glossterm&gt;Irrelevant&lt;/glossterm&gt;
&lt;glossdef&gt;
&lt;para&gt;If you can see this, the document was processed incorrectly. Use
the &lt;parameter&gt;glossary.collection&lt;/parameter&gt; parameter.&lt;/para&gt;
&lt;/glossdef&gt;
&lt;/glossentry&gt;

<para>
If <parameter>show.revisionflag</parameter> is turned on, then the stylesheets
may produce additional markup designed to allow a CSS stylesheet to
highlight elements that have specific revisionflag settings.</para>

<para>The markup inserted will be usually be either a &lt;span&gt; or
&lt;div&gt; with an appropriate <literal>class</literal>
attribute. (The value of the class attribute will be the same as the
value of the revisionflag attribute). In some contexts, for example
tables, where extra markup would be structurally illegal, the class
attribute will be added to the appropriate container element.</para>

<para>In general, the stylesheets only test for revisionflag in contexts
where an importing stylesheet would have to redefine whole templates.
Most of the revisionflag processing is expected to be done by another
stylesheet, for example <filename>changebars.xsl</filename>.</para>

<para>If you want type math directly in TeX notation in equations,
this parameter specifies notation used. Currently are supported two
values -- <literal>plain</literal> and <literal>latex</literal>. Empty
value means that you are not using TeX math at all.</para>

<para>Preferred way for including TeX alternative of math is inside of
<tag>textobject</tag> element. Eg.:</para>

<programlisting>&lt;inlineequation&gt;
&lt;inlinemediaobject&gt;
&lt;imageobject&gt;
&lt;imagedata fileref="eq1.gif"/&gt;
&lt;/imageobject&gt;
&lt;textobject&gt;&lt;phrase&gt;E=mc squared&lt;/phrase&gt;&lt;/textobject&gt;
&lt;textobject role="tex"&gt;&lt;phrase&gt;E=mc^2&lt;/phrase&gt;&lt;/textobject&gt;
&lt;/inlinemediaobject&gt;
&lt;/inlineequation&gt;</programlisting>

<para>If you are using <tag>graphic</tag> element, you can
store TeX inside <tag>alt</tag> element:</para>

<programlisting>&lt;inlineequation&gt;
&lt;alt role="tex"&gt;a^2+b^2=c^2&lt;/alt&gt;
&lt;graphic fileref="a2b2c2.gif"/&gt;  
&lt;/inlineequation&gt;</programlisting>

<para>If you want use this feature, you should process your FO with
PassiveTeX, which only supports TeX math notation. When calling
stylsheet, don't forget to specify also
passivetex.extensions=1.</para>

<para>If you want equations in HTML, just process generated file
<filename>tex-math-equations.tex</filename> by TeX or LaTeX. Then run
dvi2bitmap program on result DVI file. You will get images for
equations in your document.</para>

<warning>
  <para>This feature is useful for print/PDF output only if you
    use the obsolete and now unsupported PassiveTeX XSL-FO
    engine.</para>

<para>Graphic widths expressed as a percentage are problematic. In the
following discussion, we speak of width and contentwidth, but
the same issues apply to depth and contentdepth.</para>

<para>A width of 50% means "half of the available space for the image."
That's fine. But note that in HTML, this is a dynamic property and
the image size will vary if the browser window is resized.</para>

<para>A contentwidth of 50% means "half of the actual image width".
But what does that mean if the stylesheets cannot assess the image's
actual size? Treating this as a width of 50% is one possibility, but
it produces behavior (dynamic scaling) that seems entirely out of
character with the meaning.</para>

<para>Instead, the stylesheets define a
<parameter>nominal.image.width</parameter> and convert percentages to
actual values based on that nominal size.</para>

<para>The value of this parameter specifies profiles which should be

parameter.</para>

<para>This parameter has effect only when you are using profiling

<warning>
<para>Note that <tag class="attribute">role</tag> is often
used for other purposes than profiling. For example it is commonly
used to get emphasize in bold font:</para>

<programlisting>&lt;emphasis role="bold"&gt;very important&lt;/emphasis&gt;</programlisting>

<para>If you are using <tag class="attribute">role</tag> for
these purposes do not forget to add values like <literal>bold</literal> to
value of this parameter. If you forgot you will get document with
small pieces missing which are very hard to track.</para>

<para>For this reason it is not recommended to use <tag class="attribute">role</tag> attribute for profiling. You should
rather use profiling specific attributes like <tag class="attribute">userlevel</tag>, <tag class="attribute">os</tag>, <tag class="attribute">arch</tag>, <tag class="attribute">condition</tag>, etc.</para>
