I'm confused by the "parser...does not recognize the MML prefix" because 
it's not a parser issue--that is, either the topic is valid with respect 
to its governing DTD or schema or it's not. When authoring a document it 
would not be possible to create one with the wrong prefix assuming the 
editor is syntax driven or I'm validating as a I go.

Once I get to the point of processing, anything that is MathML-aware 
better by gosh be looking for the MathML namespace URI and not a 
particular prefix. If my processor is in fact expecting a particular 
prefix then my processor is broken, which is a "my processor is broken" 
issue, not a namespace prefix or DTD vs. schema problem.

If somebody has the expectation that they can take two topics created 
using different local schemas (DTD or XSD doesn't matter) and blindly 
smash them together into the same document instance then they are simply 
not thinking clearly because it's never possible if you expect to use 
one or the other of the original document's DTDs to validate the result, 
as a general case (of course it might work in a particular case but that 
would just be coincidence).

Cheers,
