RE: Significant W3C Confusion over Namespace Meaning and Policy

I tend to agree with Patrick. Should there really be a single RDDL document for the XSLT namespace even though there are significant differences between v1 and v2 or identifiers and representations for each distinct version of XSLT? Given a choice I'd prefer the latter to the former. 
 
Perhaps versions shouldn't be indicated via opaque strings or numbers but instead be URIs which dispense RDDL documents when dereferenced.

You assume that the interpretation of a term varies from one version of
a model to another. In practice, that's not unheard of but uncommon.
Most of the time, the same terms carry the same meanings from one
version to the next. It's only the new terms added in new versions that
take on new meanings.

Of course a RDDL document can contain content that's specifically
relevant to particular versions of a vocabulary. That's what the
xlink:arcrole attribute is used for.
