I won't dispute "reasonable".  But as I expressed in telecon, there are 
equally reasonable alternative views of it.  Effectively, the functionality 
of the 1.0 subset of 2.0 is being subject to higher quality criteria to be 
reaffirmed in 2006, than were applied to accept it as Recommendation in 
1999 and 2001.  The appropriateness of that can be debated (W3C Process is 
silent about such specifics).

And it is this potential that worries me.  If the suggested quality 
criteria for the 1.0 subset had occurred to us earlier, we could have been 
working on this for the last year or so, in parallel with developing the 
new 2.0 tests.  (In which case it wouldn't be an issue.)

I don't understand this comment, "regroup the two suites into a single 
one".  Explain?

Trivial.  (Actually, I can generate the *empty* new matrix easily from a 
list of test names, which I have.)

However, once we go from 40 tests to 250+ tests, it is questionable whether 
manual construction and maintenance of the new matrix (editing an HTML 
table) is practical or reliable.  Some automation is likely 
necessary.  E.g., vendors submit their results in a rigorous format -- even 
a careful XHTML table would suffice -- that can be merged automatically by 
XSLT.

I can write such XSLT, but haven't done so yet because ... too lazy, and 
too hard to get people to adopt rigor in submitting results, so that 
hand-editing 40 row HTML table has been easier, especially with few and 
infrequent changes.

I object to that suggestion, unless you mean "spot check".  I don't have a 
problem with spot-check.  But we should NOT require a full verification of 
results, if that's what you mean.  That is inappropriate (IMO), and without 
precedent (AFAIK).   (Not to mention more work and delay.)

No strong opinion.  I'm slightly pessimistic about anything involving 5 
vendors/implementations and 250+ (1.0) tests being done quickly.

For now, I'm preceding with the "lumpy" composite table, i.e., the one at 
the granularity of the ICS.  I'll have something soon.  (And possibly the 
issue will become moot, except for the labor to do the new 1.0-subset table.)
