Hi Thierry (et al),

Thanks for the offer.  For now, I'm just waiting for initial results from 
each of the 4 implementations, and then I will have the first draft of the 
2.1 add-on document ready to put onto the WG site.

There is something that I have been thinking about, that might be an 
interesting discussion for email and next telecons.  Consider the full 2.1 
spec, and what the full 2.1 Test Suite (TS) consist of:

2.1 Spec:
WebCGM 2.1 = As  (plus/minus) Bs  (plus)  Cs
As:   WebCGM 2.0 (w/ approved errata rolled in)
Bs:   a very small number of changes for deprecation/obsoletion
Cs:    new WebCGM 2.1 functionality

2.1 Test Suite:
WebCGM 2.1 TS = At  (plus/minus)  Bt (plus)  Ct
At:    WebCGM 2.0 TS
Bt:    a very few adjustments to 2.0 tests for errata & obsoletion/deprecation
Ct:   "add-on" module of new 2.1 tests for new 2.1 functionality.

The 2.1 add-on module contains 40+ tests.  The basic 2.0 TS contains about 
300 tests.

The document that I'm putting together now is essentially a 2.1 add-on to 
the existing 2.0 document [1], corresponding to the module of new 2.1 tests 
that are to be added to the existing 2.0 TS.  (For the sake of simplicity, 
I'm ignoring the very few changes for errata & obsoletion/deprecation for 
the moment.)  So we might be looking at a new bullet in the "Implementation 
Results" section of [1], that points to the new 2.1 add-on implementation 
table that I'm building.

[1] http://www.w3.org/2006/Graphics/WebCGM/implementation-report.html

This raises an interesting question or two.  Should the 2.1 Implementation 
Report effectively cover only the 40+ new 2.1 tests, and point to the old 
2.0 report?  (With a very exceptional entries for the very few 2.0 things 
that changed due to errata, obsoletion, deprecation.)

While it might interesting to see today's implementation results on the 
whole 340 tests, on the other hand 300 of those tests cover features that 
are already REC.  They (and associated 2.0 features) went through the 2.0 
CR-exit process 2-3 years ago, and are certainly not subject to removal 
from 2.1 REC as an outcome of the 2.1 CR exit process.

So I'm thinking that the 2.1 report ought to have the test-by-test 
implementation table (40+ rows) for the new 2.1 features, plus a small 
test-by-test table for 2.0 features that might have changed status (errata, 
obsoletion, deprecation) if there are any such, and could include an 
informative pointer to the 2.0 Implementation Report.
