I think there are two related questions about the rdf attributes
(about, ID, resource, etc..) . The first is how to deal with them when
they are specified on an element from the RDF namespace. The second is
how to deal with them on all other elements. 

The examples in the specs and some of the postings to rdf-comments
indicate that the rdf attributes should be unqualified when specified
on an rdf element and qualified when specified on a non-rdf element
(see Ralph Swick's comments in [1] for example). 

There is a question whether an RDF processor should treat
RDF-qualified attributes on RDF elements as equivalent to the
unqualified attributes. This has also been brought up and Tim Bray
responded to it [2] saying that they can (but aren't required to) be
viewed as equivalent. 

The example you bring up is of an unqualified attribute that is being
treated as qualified by the  RDF namespace when on an element that is
not from the RDF namespace. I don't think that this falls under any
interpretation of the namespace spec. 

It does match up with the formal grammar and some (but not most) of
the examples in the M&S spec. I look forward to hearing some
unambiguous guidance from the editors on this issue. BTW, where can we
find the errata/issues list for the M&S spec?
