(b) is the only interesting requirement at this time. Some people are
convinced (admittedly, others aren't) that there are useful things you can
and will want to do based only on the information that some data object
claims to use XML syntax. Thus the main goal here is to get something in
at the MIME level to signal this case.

I agree entirely. There is lots of work to do to figure out how to
package up, transmit, and process multi-vocabulary XML documents, and I'm
far from convinced that the MIME layer is going to be the right place to
do it (although it's an option that needs to be examined closely). But
that's not the problem that Murata/St. Laurent are trying to solve. -Tim
