I think we should eliminate vtrav and all other derived Versa
namespaces, and just use the main Versa namespace.
Also, are we committed to the namespace as the primary vehicle for Versa
versioning? This can be a sticky choice, but then again, all of them
can be.
And remember that we now have rdfversa.org, and see my earlier namespace
suggestion.
