My interpretation was that MathML will *not* be a subset of XHTML IM. 
This XHTML IM JEP is related to MathML only in that a future MathML JEP 
may want to go along the lines of the XHTML IM JEP. Maybe in the future 
there could be MathML embedded in the XHTML IM as well, but for now I 
think we should deal with them separately. I dunno.

I think that's up to the MUC JEP to decide. :) I think it would make 
sense that a disco request to the room returns whether it wants XHTML 
messages or not. It would work fine with the existing XHTML IM JEP in 
that a disco request needs to be sent first.
