Graph naming?

This reminds me of one of those simple ideas that's been kicking around my 
head for a while, but I don't think I ever expressed...

Notation3 (as I understand it) has a simple way of creating named graphs 
within a document;  the idiom I use is:

    uri :- { <formula> }

It would be a small extension, I think, to do something similar with RDF/XML:

    <rdf:RDF rdf:ID="foo">
      :
     (RDF statements)
      :
    </rdf:RDF>

or

    <rdf:RDF rdf:about="uri">
      :
     (RDF statements)
      :
    </rdf:RDF>

Thus, an RDF element might be treated as a syntax construct for a node that 
happens to be a graph.

Is this conceptually broken in any way I haven't noticed?
