The language in the Namespaces REC means that the two *can* be
distinguished, not that they must be, and every Namespaces-based spec
should include a explicit statement of its usage.  Based on the
examples in the spec, RDF, for example, doesn't distinguish

  <rdf:Description about="">


  <rdf:Description rdf:about="">

and I'll note that it is entirely conformant in not doing so.  In
XHTML, likewise, we have to infer what its usage is from examples
unless the WG gives us a explicit statement.

All the best,
