The MathML errata document for MathML 2.0 Rec, and the draft text of
MathML 2 2nd edition both make it clear that the DTD in
http://www.w3.org/Math/DTD
supersede the DTD distributed with the Rec in http://www.w3.org/TR/MathML2

Some of the "errata" items in the dtd were not really errors but just
phrasing things in officially equivalent ways that work (rather than not
work) with certain well known parsers.

In addition to constraints placed on the DTD by IE, mozilla has its own
(different) constraints on th eIDs used for DTD (not the content, as it
doesn't read them). Generally I recommend not using a doctype at all
for published documents (see for example the format used in the test
suite) as if you use a doctype IE will really fetch the DTD which in
many cases is a much bigger download that the actual MathML document.

This came up last week on this list. I was sure that it did say
something about that, but it certainly doesn't. I'll try to add some
text, but as Robert indicated, my MathML time is somewhat taken up with
MathMl 2 2nd edition just at present.

Suggestions welcome!
