This would indeed finesse the problem.  Hmm, three questions on the notion
of detecting whether content is XML:

1. is it possible in principle in the general case?
2. if not, is it possible often enough to be useful?
3. is it an appropriate kind of thing to require a general-purpose
   MIME handler to do?

I'm pretty sure the answer to #1 is "no".  However, my intuition is that
the answer to #2 is "yes".  I don't have an opinion on #3.  The code isn't
that hard to write.  But should a MIME hander have to care?

I'm getting backed into a corner where, like it or not, the -xml convention
is looking substantially less bad than all the alternatives.  As for
charset, if the people who are asserting that we have to support fallback to
text/plain are right, then it's gotta be compulsory.  -Tim
