DefinedNamespace package
Proposed replacement for the current rdflib ClosedNamespace module.
The general notion is that, unless the warning flag (_warn) is set to false, a warning will be issued whenever an
element in a namsepace is referenced that isn't formally defined.
The definitions in the classes allow IDE's to do search and substitution.
See: tests/data/RDF.py , tests/data/SKOS.py and tests/data/RDFMOD.py for examples.
