    This XML Schema corresponds to V3.18 of Password Safe.
    This describes keyboards that cannot be extracted or need extra changes.
    Each keyboard must have a unique keyboard layout ID (KLID) and name.
    To make different from those in Winodws, these should end with 'FFF'.
    The Japanese keyboard is different as there are XX versions.
    
    Each keyboard has keys denoted by their scan code,  and then the 
    definition of the Unicode characters. Dead Keys and Multi-character
    values are not supported.
      b = base character (pressing the key without shift, caps, control or alt keys)
      l = with the Left Control key
      g = with the Alt Gr key
      r = with the Right Control key
    Then each of these can be with or without the Shift and Caps Lock key
      C = with the Caps Lock key
      s = with the Shift key (left or right)

    Giving four sets of four:
      "b, bC, sb, sbC", "l, lC, sl, slC", "g, gC, sg, sgC", "r, rC, sr, srC"
