Hi Thierry,

Thanks for getting this started.

I have one comment for now, embedded...

We should pay attention to a subtlety of wording here.  WebCGM 2.0 includes 
the functionality of WebCGM 1.0, plus new stuff for 2.0.  The WebCGM 2.0 TS 
includes the WebCGM 1.0 TS, plus new 2.0 tests.

WebCGM 2.0 is not a "delta" specification, and neither is the WebCGM 2.0 
Test Suite a "delta" (in my view of things).  On the other hand I think 
this exit criterion does need to be "delta".  I.e., there should be two 
passing implementations for every *new* 2.0 feature.

Why?  Because 1.0 is already a Recommendation, since 1999.  That was before 
the present CR/exit-criteria stuff was part of W3C process/convention 
(correct?).  Although I fully expect that there are at least two "pass" for 
every one of the existing 254 1.0 tests, on the other hand it is somewhat 
academic, because we can't rescind features of the 1.0 Recommendation if not.

Viewed another way, we shouldn't attempt "ex post facto" to apply more 
recent W3C Process conventions to content of existing Recommendations.

(All)  Does this make sense?

Yes, it is on the just-sent agenda.

Thanks,
