I agree with danny here, and I think the WG would also agree with danny. 
 <http://somewhere/me.rdf> identifies a document.  Which is why we need 
#ThisGraph.  There is currently nothing to refer to that *abstract* 
thing.  The document is a tangeable physical thing that contains token 
strings.  The graph is an abstract thing that contains triples.  The 
parser in an application will turn the token strings from the document 
into triples in the application's database.  If we are to talk about 
this distinction in an interoperable manner, then we need a *standard* 
way to refer to the document as opposed to the graph.  

Does begging work with the WG ?
