CSS versioning: exemplary? exceptional?

At the TPAC in November, TimBL mentioned tag soup and validation
and there was some follow-on discussion (in IRC at least)
about CSS's versioning policy

Our current draft doesn't seem to say much about CSS:
[Editorial Draft] Extending and Versioning Languages: Compatibility
Draft TAG Finding 28 March 2008

but it does say

"Language Identification rule: Any Languages intended for versioning
SHOULD have a version identification strategy"

Is CSS an exemplary application of that rule? or an exception to it?
or something in between?
