I was thinking this bit didn't need to be explained in all its detail.    It could be easily done with a full URI ("for example, if the following document were published at http://example.org/ex1"). 

Also, <> is an idiom that's incredible popular in turtle (and equivalent in other rdf syntaxes, like rdf: about="").   It's hard to imagine someone getting very far with RDF not knowing it.

It seems to me the beauty of <> is that it works even when the trivial url differences crop up.   Reading it as "this document" glosses over the machinery very elegantly.
