That would be the TAG. As it happens, it's already working on versioning and extensibility.

Namespaces aren't version identifiers, they're just that: namespaces. Rare are the languages that change their namespaces when they modify the vocabulary: XHTML and SVG don't do that for instance, and I'd be very surprised — shocked in fact — if XForms did. -- Robin Berjon Research Scientist Expway, http://expway.com/Received on Wednesday, 9 February 2005 18:31:38 GMT
