     ChangeLog: (See also: CVS ChangeLog)

     15 August 2002: Norman Walsh, <Norman.Walsh@Sun.COM>
       - Version 1.3 released at http://www.w3.org/2002/xmlspec/html/1.3/xmlspec.xsl
         There have never been any "official" releases before, so the version number
         is arbitrary.

     15 August 2001: Hugo Haas <hugo@w3.org>
       - Slightly modified the status sentence introducing editors'
         copies.
       - Now using role to distinguish editors' copies: e.g.
         <spec w3c-doctype="wd" role="editors-copy">

     14 August 2001: Hugo Haas <hugo@w3.org>
       - If w3c-doctype is not a W3C TR, do not use a Note style
         sheet, use <http://www.w3.org/StyleSheets/TR/base.css>
         instead.
       - If the other-doctype is "editors-copy", do not use the W3C
         logo and mark the document as such in the status section.

     12 Jun 2001: (Norman.Walsh@Sun.COM)
       - Support non-tabular examples. If tabular.examples is non-zero,
         tables will be used for examples, otherwise nested divs and
         CSS will be used. tabular.examples is *zero* by default.

     06 Jun 2001: (Norman.Walsh@Sun.COM)
       - Support copyright element in header; use the content of that
         element if it is present, otherwise use the auto-generated
         copyright statement.

     15 May 2001: (Norman.Walsh@Sun.COM)
       - Changed copyright link to point to dated IPR statement:
         http://www.w3.org/Consortium/Legal/ipr-notice-20000612

     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>.

   5 June 2001, Henry S. Thompson (ht@cogsci.ed.ac.uk)

       - Fixed a link in copyright boilerplate to be dated
