'Consistent with the URI spec' and 'consistent with the use of URIs in
Namespaces in XML' - which is strictly as names - seem to be thoroughly
incompatible, at least from your viewpoint.  

I'd appreciate it if you could explain why you it is so critical that lower
layers of processing handle the considerable amount of effort involved in
treating URIs _as URIs_ rather than as strings for purposes of comparison,
and why higher layers (like RDF and other models) can't be trusted with
that responsibility.

In short, explain your side of:
