Perhaps I could make the (fairly obvious) point that if incoming triples
are added to a model, which changes over time, the model may not be
"reasonable" RDF until they have all arrived, e.g. if arbitrary parts of
an RDF:Bag arrive, or parts of a reified statement.  A hierarchical
structure of triples may not make sense until all parts have arrived.
