This question ties to a few others that have come up.

My response would be this is just XML, since nothing says otherwise.

The caveat is that if we allow RDF to omit rdf:RDF and rely on well-known
namespaces then we have to figure out a way to answer the question for a
parser - i.e. is it legitimate to rewrite this as

  <rdf:RDF>
    <rdf:Description about="">
      <dc:title>This is a title</dc:title>
    </rdf:Description>
<foo id="barfoo">
  <bar>lorem ipsum</bar>
</foo>
  </rdf:RDF>

or not?

We could also wonder what the namespace says - does it provide an XML schema,
or an RDF schema, or something else, or both? Does it answer to a request for
something that transforms from one to the other?
