I totally agree.  I really don't understand why we can't just agree to
refer to the set of triples (the model) encoded by the document at
<urlA> as <urlA#ThisGraph>.   Sure we can do that right now, but it
would be nice if the WG could standardize on some fixed constant  like
"ThisGraph" so that our data would be interoperable.    Why does the WG
seems to think that its reasons for not specifying this are *more
important*  than it is for developers to have some standard way to refer
to a model as a "first class entity" ?
