<!-- Stylesheet for @diff markup in XMLspec -->
<!-- Author: Norman Walsh (Norman.Walsh@East.Sun.COM) -->
<!-- Date Created: 2000.07.21 -->
<!-- This stylesheet is copyright (c) 2000 by its authors. Free
distribution and modification is permitted, including adding to
the list of authors and copyright holders, as long as this
copyright notice is maintained. -->
<!-- This stylesheet attempts to implement the XML Specification V2.1
DTD. Documents conforming to earlier DTDs may not be correctly
transformed.
This stylesheet supports the use of change-markup with the @diff
attribute. If you use @diff, you should always use this stylesheet.
If you want to turn off the highlighting of differences, use this
stylesheet, but set show.diff.markup to 0.
Using the original xmlspec stylesheet with @diff markup will cause
@diff=del text to be presented.
-->
<!-- ChangeLog:
25 Sep 2000: (Norman.Walsh@East.Sun.COM)
- Use inline diff markup (as opposed to block) for name and
affiliation
- Handle @diff='del' correctly in bibl and other list-contexts.
14 Aug 2000: (Norman.Walsh@East.Sun.COM)
- Support additional.title param
27 Jul 2000: (Norman.Walsh@East.Sun.COM)
- Fix HTML markup problem with diff'd authors in authlist
26 Jul 2000: (Norman.Walsh@East.Sun.COM)
- Update pointer to latest xmlspec-stylesheet.
21 Jul 2000: (Norman.Walsh@East.Sun.COM)
- Initial version
