It should say that implementations use intrisinc knowledge derived from
the media type registration to determine whether or not the type used to
label the entity body is an XML media type, persumably one that is meant
to be used for complete document entities rather than other entities as
those cannot yield in a Document. We might optionally want to require
that the corresponding types in RFC 3023 and any type that follows the
+xml convention is recognized as XML document in accord with RFC 3023.

It would not make much sense for a user agent to specifically not re-
cognize specific media types as representing XML documents for the pur-
poses of XHR processing when the user agent does that everywhere else.

Not following the +xml convention is not technically illegal.
