I'm not clear what is the issue about MathML
Names. If there is a character-set encoding issue, I think that
can be handled in the <?xml> prolog element for free-standing
MathML XML documents. What non-Unicode are you encountering?
</orcnote>
It is not about encoding, but about an entity reference like ∫
instead of the numeric XML character references ∫ or the literal
character ∫.

Ah! Character entities. Yes that is a problem.
Hmm, perhaps a standalone internal DTD could be used to define these.
I am not certain how one gets around DTD validation.
It would be nice
to use the character entities rather than the character references.
I would avoid the literal characters of course, because their being
understandable depends on font availability.
Does the MathML DTD provide definitions that could be moved to an
internal DTD?
Perhaps a brief experiment to see if that much will be accepted by
the SAX parser?
</orcmid>
Some brief experiments: When I use version A or B (see below) the
reference ∫ is not resolved. The browser Seamonkey resolves it
in both cases, so I assume that the syntax and URI is correct. The
version C is resolved correctly by Apache OpenOffice, Seamonkey and Word
2010 but not by LibreOffice; which shows, that the error is likely
inside LibreOffice.
The mappings are in a file "mmlalias.ent" but I don't know, how I can
link to it in the doctype declaration.
I see no problem in using a literal character, because such character
itself has no binding to a font. When you try version C, you will
notice, that the integral sign is the same in all three occurrences.
Kind regards
Regina
