Joey,
	I think a little more investigation is required. For a start if I purge 
w3c-sgml-lib and install w3c-dtd-xhtml no such file is found in a manual 
inspection of the file system. Issues that I thought were related and an 
indication of something seriously wrong, turned out to be minor and 
unrelated. Using xmlcatalog I cannot see any obvious incompatibility. In 
theory I should install wdg-html-validator and try and work out what it 
is doing to fail, but I would rather avoid that as the package is 
orphaned and I would feel compelled to adopt it and I already have 
enough (if not too many) Debian commitments.


	I would really appreciate it if someone could point out what 
wdg-html-validator and I could put that in a script as an integrity 
check inside w3c-sgml-lib.

	Then there is the more general question of why I did things the way I 
did. I wanted to discuss this six months ago when I started working on 
the w3c-markup-validator but there were few takers. w3c-sgml-lib is 
intended as a direct substitute for w3c-dtd-xhtml. Both packages have 
the same upstream source. However the w3c-dtd-xhtml has an arbitary 
layout that bears no relation to the upstream. Whereas w3c-sgml-lib 
attempts to follow upstream but provide soft links that give backward 
compatibility. Obviously I hope w3c-dtd-xhtml will be phased out.

	If it turns out that there is a genuine incompatibility between the two 
packages then I would have to add a Conflicts clause rather than the 
current Breaks/Provides. However that would seem to be less than ideal.
