I started out thinking that relative URI references were evil creatures
that should be disallowed entirely in namespaces, but wind up at a similar
position: compare namespace URI references (including relative ones)
literally, char-by-char, and let higher levels handle absolutization when
needed.  

Relative URI references need warning labels, but I think that can be
handled as best practices rather than specs.
