I think that, in general, it is far more effective to require that
a namespace identifier be in a restricted, canonical form, than it
is to require all parsers to perform URI-equivalence operations
when comparing two namespaces.  Much more efficient as well.

In other words, simply require that all case-insensitive parts of
the URI be lowercase and all non-reserved data characters be unencoded
as part of the definition of valid xmlns values.  Then all of the
parsers can simply perform byte comparison.
