This seems to me a trick for truth value maintenance
over the whole set of sentences involved in reification.
I think that the notion of atomicity in reified
sentences should be considered and a syntax needs
to be in place.  A <start> and <stop> or <begin>
and <end> can bring atomic notions of reified
sentences in RDF just like in high level programming
languages.
