[Om3] OMS and OMV contents?

[Michael Kohlhase]

Dear all,

one thing we have to think about wrt. OM3/MathML3 alignment is whether 
we want to allow presentation MathML in the body of OMV and OMS 
elements. I know we have discussed this before (for OM2) and rejected 
it, but with the alignment goal this question raises it's ugly head again.

Allowing full presentation MathML content would quadruple the size of 
the RNC schema (well we would just add a link of course) or add an 
external dependency.

Going for a restricted set of presentation MathML would be nice (who 
needs mtable in a variable name), but would require furer coordination 
with the W3C Math group.

The OM2 standard allows to add presentation MathML as a special 
attribution, but that is much less direct than MathML does make the 
alignment non-isomorphic.

Any thoughts?

Michael
