No! the (rather regretable) dated W3C namespace URI are explictly _not_
for versioning, it's just that the W3C uses a dated format for any URI
that they intend to be permanent.
The date just indicates when the namespace name was allocated.
so for example
is the namespace for MathML 1, 1.01 and 2.0 (and hopefully all future
versions of MathML)
is the namespace for XSLT 1 and for the XSLT 2 proposal.
(these older ones just have years, W3C started using months more
The dated format is unfortunate as it leads people to expect the URI to
change when a new version of the language is released on a later date,
but that's just the way it is.
