[where "some sort of document" may be defined as a query and not a static
bucket of bits...]

But then it shouldn't now say that the URIs used by XML Namespaces _must_
be unique.

It should say "Think twice before using one that is not reliably unique."

The following compromise reflects a reasonable balance of backward and
forward compatibility:

a) perform syntactic processing based on literal comparison of ns-attr

b) save for post-syntactic processing any context information implicated in
the evaluation of xml:base; if this varies across namespaces in the
document, save the relation.

c) Warn on non-globally-unique ns-attr
