The MIME type isn't really useful once parsing has begun.  Namspaces are 
used for dispatching elements to the right place.

AIUI, generally speaking, the MIME type used should be that of the host 
language, which is determined by the root element.  While authors 
probably shouldn't use application/xhtml+xml for such documents, there 
is little problem in doing so because of namespaces.

If in doubt, application/xml is always available for use.
