Oooh, so it does!  I missed that.

Dan:  should this be on the issues list?  Is there any reason not to be 
able to make statements about bags that are defined elsewhere?

Looking at this, I realize the RDF M&S syntax is actually ambiguous.  Consider:

    <rdf:Bag>
       <li>foo</li>
    </rdf:Bag>

This matches syntax productions [20] and [17].

In one sense, that's true, but I think it is also possible to simply ignore 
that part of the spec and build similar structures without actually 
breaking RDF.  It's sneaky, but I don't think there's anything in RDF to 
prohibit that (which is effectively what I done with my contexts proposals).
