Namespaces only make sense in a world where you can more or less randomly
mix objects from different problem domains. That very seldom happens in
the document world. It would require some way to dynamically assemble
processing specifications (stylesheets). But the interaction between
stylesheet levels is way too complex for this sort of dynamically assembly
to be easy. We also know that dynamic assembly of schemas is quite tricky.
As far as I know, nobody is doing it yet. So the namespace mechanism
strikes me as premature considering that we don't have any infrastructure
to take advantage of it.
Note that XSL takes advantage of namespaces in the stylesheet by merely
dispensing with a schema altogether. As far as I know, XSL has no facility
for dynamically assembling stylesheets *based on* namespaces.
RDF has a sufficiently simple "processing model" that it makes sense to
talk about combining data from various "namespaces" into a single RDF
model. But useful applications built on top of RDF (both of them) will not
(IMO) usually take advantage of the namespaces mechanism. For instance
Netscape's "What's Related" may be RDF-based (I can't remember) but it
probably does not support arbitrary namespaces.
