Unless otherwise provided by information outside the scope of this
specification (e.g. a special XML element type defined by a particular
DTD, or a processing instruction defined by a particular application
specification), relative URIs are relative to the location of the
resource within which the entity declaration occurs.

I agree that the system identifier in the doctype decl. can't reasonably
be overriden by xml:base as xml:base is specified today. But other
system identifiers can be; public/system applies to all external
entities, of course.

I think we've wandered off topic a little, if there was a topic :)

Relative namespace URIs are of course discouraged.
