(like Graham, I think I'd rather endorse
InterpretationProperties/datatype properties
while we're at it. But since that can be done
later, and the whole point of this proposal
is to be minimal, it's not critical.)

I kinda like this, but I'm afraid there's quite a lot of details
to work out with rdf:datatype

This is gonna clash (unacceptably) badly with existing RDF parsers
and with what knowledge users have managed to pick up about RDF

Costs too much to deploy; undermines the connection between
