I've noticed this assumption behind a lot of the Namespace-related
postings (not just Len's) -- I guess it would be a good thing to have
a global resolution mechanism of some kind, but I'm surprised that
people consider Namespaces incomplete without this.
After all, there's nothing similar for (say) Java or Perl package
names, and while having something like that would be convenient (and
CPAN is very nice as far as it goes), the absence of a global
resolution mechanism for figuring out what org.xml.sax or XML::Parser
means doesn't seem to inhibit useful work in Java or Perl.
Why is XML different? Is it just that we come from the SGML
background, where we consider structural validation to be part of a
document rather than a process applied to it, or is there some kind of
a fundamental difference between naming code and naming document
nodes that no one has articulated yet?

No, that's too long -- I need something shorter and catchier.
All the best,
