It seems to me that  "_:s rdf:subject _:s"  is not a self referencing
triple.  In fact I dont's see how you could even write a self referencing
triple in RDF at all, since RDF does not even provide for triples to have an
identity.  In the example above "_:s" is the identity of the thing of type
Statement, not the identity of the triple.

Help, I'm confused  ?
