> Does this newsgroup post solve your problems
YES! It does solve my problem. (I did perform an extensive search on Google,
but not in the groups... Shame on me!)
So: that post explains the situation for the entity "lt", which seems to be
bogus indeed in the XHTML Modularisation Specification (I would like to know
the HTML gurus' opinion on this one). My (very similar) problem was in fact
with the "amp" entity, but of course the lt one popped up right after.
Solution: I simply redeclared lt and amp in my "driver" file like this:
<!ENTITY lt "&#60;">
<!ENTITY amp "&#38;">
That was enough for MSXML to accept my modularised DTD.
I did further tests with the "bogus" DTD and the other parsers. I think it
can be interesting to report that here. I simply added "<" somewhere in
my sample XML instance and tried to validate it. Results:
- Xerces 2.0.1 validates, which is wrong.
- XMLSpy validates too.
- ElCel's xmlvalid 0.14.7 doesn't and reports:
xhtml-special.ent [37:20] : Fatal error: entity reference
must start with a letter, '_' or ':'
Note that the lt entity is in fact on line 35, not 37.
- libxml2 doesn't and reports:
Entity: line 1: error: xmlParseEntityRef: no name
Entity: line 1: error: xmlParseStartTag: invalid element name
sample7-id.xml:14: error: Entity value required
html:li id="N10058" class="Text" title="Text" xml:lang="Text">Text
test lt: <
I suppose the last 2 don't even check the entities before they are actually
used. Call it a feature or a bug. Anyway, I think MSXML could be more
specific in pointing the error. "Line 1 position 2" is not very helpful.
More generally, and speaking as a user of these parsers, I think they should
output a warning about such bogus entities (and of course an error when they
are encountered in the doc instance).

Thanks to you, Dare, and for the very appropriate words of wisdom :-)
May I suggest a Knowledge Base article about this issue?
(PS: just for indexing purpose, I thought I should type modularization in
en_US somewhere. Now it's done.)
