As far as I have understood, any OASIS document handling application should 
support unknown document parts. So if we need it for OASIS, you can implement 
it for MathML too.

For my part, you can do it. Just be careful to coordinate with Laurent, as he 
plans to re-write the MathML/OASIS loading code, as far as I have understood.

Have a nice day!
