Commonly known as the framing problem. The point here is that "meaning" and "semantics" of XML elements is really only meaningful in a given application context. My assertion has always been that in such situations, namespaces don't help *except* as an alpha-renaming mechanism to aid in disambiguation. All the hubbub about "semantic discovery" and "downloading semantics" etc. etc. is nonsense. People have been trying to do this with agents for years (KQML et al.) and have met with only partial success. Will it be possible eventually, I think so. Right now, absolutely not. As such, the trick now is to package the XML, and the interpretation context for the application (ie. how to package the application).
