I could curse for a few hours about the state of namespaces and XML 
validation, but in the interest of brevity...

RSS does it, but in a very limited way.  You can't monkey around with 
content models, for instance.  That makes it a lot easier, but it's much 
more limited than just dropping in content from other namespaces wherever 
you'd like it to be.

With XHTML 1.1, that's sort of possible (you can change content models), 
though not exactly easy.
