How an application deals with an unregistered media type would seem
entirely out of scope to me.

Are not XML.

Yes, I can see how it might make sense to say something about
namespace wellformedness now that we have the concept defined.

It would be wrong to interpret such a document as XML, so it isn't
an XML document.

| XML 1.2/2.0 documents,

Why should XLink make more explicit reference to this possibility than
other specifications that use XML?

| documents

Are there any?

| documents that cannot be retrieved because the protocol is unsupported,

| and so on.

Aren't those all out-of-scope?

No, I don't think it would, but the Core WG couldn't really tell what
your question was.
