I have no idea what that means.

CSS doesn't need versioning because there is no real use case for 
versioning in CSS. (At least, I haven't yet seen one.) If you know of a 
use case, please explain it (and specifically, explain what the 
conformance criteria related to that versioning scheme would be).

Some features, such as display:marker, have been removed, yes. This has no 
effect on either implementors, authors, or users, since the features were 
never implemented and never used.

There were many fixes to CSS2, yes. CSS 2.1 is a comprehensive revision 
that fixes literally hundreds (if not thousands) of issues that have been 
raised over the years.

It has been demonstrated, e.g. in adhoc testing during F2F meetings and 
telecons, and in mails to the CSS lists. What hasn't been done is nobody 
has written a report on it (which is what I understood you were asking 
for). Writing such a report would be a massive undertaking, effectively 
summarising the CSSWG's activities for the past four years.

Hopefully the above clarifies the situation. Please explain what it is 
that you do not think follows, if not.

Did you reply to Bert's answer to your issue? I did not see a response.
