I think there's a little something more to it. When XML follows a
certain set of constraints [1], that XML can be processed as if it was a
collection of RDF triples.  RSS 1.0 was designed around that principle,
and Aaron Swartz appears to be saying [2] that P/E/A/W can fit into that
same structure very easily. 

As long as the documents stay in that structure, you can treat them as
RDF regardless of what namespaces happen to be used in them.

Once you've read it as RDF triples, DAML, OWL, and whatever other
acronyms you like can be applied to it.

This is a little different from expecting RDF to provide answers to all
namespace-mixing problems, and is probably only useful to people who are 

(a) willing to process the documents as RDF, not just XML (I'm not)

(b) believe that RDF really supplies meaning to information. (I don't.)
