Hmm... it seems a bit scary to come right out and normatively
say what's an RDF/XML document anywhere besides the RDF/XML spec.

Also, I reviewed issue-mt-ns and found that we'd have
to re-open the issue to add a rule, since
our 2007-02-07 decision was that "the current rules address
issue-mt-ns".
http://www.w3.org/2004/01/rdxh/spec#issue-mt-ns

So rather than add any normative rule boxes, I just
added this paragraph after the existing rule, citing*
a test case that we recently approved:

[[
Note that while an application/rdf+xml media type is one indication that
a document is RDF/XML, section 7.2.1 Grammar start of [RDFX] leaves open
"other means" by which an RDF/XML document may be identified. For the
purposes of the rule above, root element whose local name is RDF and
whose namespace URI is http://www.w3.org/1999/02/22-rdf-syntax-ns# is
such a means. For a case in point, see the grddlonrdf-xmlmediatype test
case.
