What does a namespace name point to became a philosophical question once
the Namespaces in XML editors decided to use URIs and not URLs. At least
if they chose URLs (or even better HTTP URLs) then one could claim that
they should always point to metadata about a namespace preferrably
multiple kinds of information such as is provided by RDDL and not just
one specific type of schema. 

However since they are URIs they are simply identifiers and not
locations so the argument doesn't hold as much water.

What do you mean by dynamically producing namespaces?

XPath doesn't understand default namespaces and thus I don't think XSLT
does either.
