there are two situations.

in a global context the uri is correct.
if one wishes to resolve a name in the dynamic context of a document or of an
element, the prefix, in addition to the uri, would be correct.

although this (the prefix qualification), in any case, is not something an
application should have to do (therefore the concern for an opaque object,
which question still stands), it is something which a specification which is
part of an encoded document would need to express. within the document itself
it would be wrong ( i won't say 'dead wrong', but it would be more cumbersome)
to specify relations among symbols and or namespace regions according to uri,
particularly given that there are already prefix bindings in effect in that
dynamic context. which is where the prefixes come in.

in global context, one shouldn't be worrying about qualification any more, the
tokens which the parser generates whould be globally unique. (the opaque
objects again...)
