Until someone comes along and wants to say:

Benji rdf:type ex:Dog
Benji pet:owner ex:AtlantaPoliceDepartment


Charlie rdf:type ex:Parrot
Charlie pet:owner ex:KeyLargoBoatHouse

What to do?  Range is something broad like "Entity"?  And when someone finds
a valid use for pet:owner with a "non-Entity"?

I'm becoming doubtful about the usefulness of global domain and range
constraints within the context of the Web -- which is fine save for its
current prominence in the RDF documentation.
