I don't know that this is as important a goal as making sure that the
names used are appropriate.

I'm guessing this also comes from your desire to minimize extension.
Again, I think it's far more appropriate to find a fitting name.

Hmm. The only "use" I see is saving a few keystrokes. But what it does
is make the processors have to do a resolution by base URI to get at the
linked resource. Also, it makes it harder to proxy/distribute
It's not a big deal either way.

Yes, but your wording everywhere on the page talks about "schemata". I
would generalize this wording so that i is clear other sorts of resources
can be catalogued.

I'd say simply "Namespace Catalog".
