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.
