  To be more precise, a subset of URI references with semantics that 
differ from URI references in general.

We'll let that pass (default ns?)

  Relative URI references are deprecated as XML namespace names.

+1

  XML namespace names are compared by string equality, i.e. not the way 
URI references are resolved. [1]

No, but as 'strings' they are uri's?

But you cannot really infer much about the semantics of XML namespaces 
from that. An XML namespace name is not a type of URI.

Tell you what Peter.
I'll ask the stupid questions.
You come back with the 'right' answers, to guide us,
and the db comittee can think about it for a while.

Agreed?
