In RDF2 we could convert rdf:about="" into a bnode, and then have #frags
as links between  bnodes and other bnodes.

e.g. allow any unicode string as a property name having extension
linking a resource with an absolute uri to a resource having the
appropriate uri-ref e.g.

<http://exampl.org/> "foo" <http://exampl.org/#foo> .

(by definition)

then if we have no base


translates to a bnode _:doc



translates to _:x and the triple

_:doc "foo" _:x .

This would allow the about="" convention and rdf:ID to all work in the
absence of a base URI.
