The example that I reported aginst the validator was one where there was
_more than one_ rdf:subject, rdf:predicate and rdf:object, _not_ a
"partial reification" example.  Some folks seem perfectly happy with
that, but they are suggesting fairly sophisticated inference to
disentangle the triples; not everyone is going to want that sort of
solution, IMHO.
