<!-- ChangeLog:

     25 Sep 2000: (Norman.Walsh@East.Sun.COM)
       - Sync'd with Eve's version:
         o Concatenated each inline element's output all on one line
           to avoid spurious spaces in the output. (This is really an
           IE bug, but...) (15 Sep 2000)
         o Updated crism's email address in header (7 Sep 2000)
         o Changed handling of affiliation to use comma instead of
           parentheses (9 Aug 2000)

     14 Aug 2000: (Norman.Walsh@East.Sun.COM)

       - Added additional.title param (for diffspec.xsl to change)
       - Fixed URI of W3C home icon
       - Made CSS stylesheet selection depend on the w3c-doctype attribute
         of spec instead of the w3c-doctype element in the header

     26 Jul 2000: (Norman.Walsh@East.Sun.COM)

       - Improved semantics of specref. Added xsl:message for unsupported
         cases. (I'm by no means confident that I've covered the whole
         list.)
       - Support @role on author.
       - Make lhs/rhs "code" in EBNF.
       - Fixed bug in ID/IDREF linking.
       - More effectively disabled special markup for showing @diffed
         versions

     21 Jul 2000: (Norman.Walsh@East.Sun.COM)

       - Added support for @diff change tracking, primarily through
         the auxiliary stylesheet diffspec.xsl. However, it was
         impractical to handle some constructions, such as DLs and TABLEs,
         in a completely out-of-band manner. So there is some inline
         support for @diff markup.

       - Added $additional.css to allow downstream stylesheets to add
         new markup to the <style> element.

       - Added required "type" attribute to the <style> element.

       - Fixed pervasive problem with nested <a> elements.

       - Added doctype-public to xsl:output.

       - Added $validity.hacks. If "1", then additional disable-output-escaping
         markup may be inserted in some places to attempt to get proper,
         valid HTML. For example, if a <glist> appears inside a <p> in the
         xmlspec source, this creates a nested <dl> inside a <p> in the
         HTML, which is not valid. If $validity.hacks is "1", then an
         extra </p>, <p> pair is inserted around the <dl>.
