Yes, fine... but that's not the issue is it? The issue is whether the
namespace URI should point directly at the canonical schema or whether it
should point to something else (RDDL) that points to the canonical schema?
I think the namespace URI should resolve to something that provides human
and machine-readable links to
- the canaonical schema
- other versions of the schema
- human readable versions of the schema
All of this could be done using hard-coded URLs :-( or via appropriate
links to the registry :-). RDDL looks, to me, like a good candidate
language for providing these linkages. Otherwise, how is someone going to
get from the namespace URI to the registry?
