I maintain that the issues raised in #rdf-formal-sematics are not adequately
addressed in the model theory, and that this issue should not be closed.

In particular, the current model theory does not address reification at
all, so there is no sense that it can be used to close an issue whose
summary asks:
	What is the relationships between a statement and its reification.

The current model theory does address collections, but its treatment of
collections leaves much to be desired.  In particular, rdf:Bag is not a bag
at all, but instead is much more like a sequence.  If rdf is going to have
something called rdf:Bag, then its *RDF* semantics should conform to the
intended meaning of bags!
