I have been thinking about this question.

One way to identify them as 1.0 files is to put them in a place that says, 
"all of these 1.0 tests are valid 2.0 tests".  The other way is to change 
the "1.0" to "2.0" in the MetDesc element in the CGM, to also make that 
change in the graphical text that labels and appears in the legend block of 
the CGM, and regenerate all of the PNG files.

I have done something like the latter before, when adapting tests from ATA 
to WebCGM.  It's a bit of work.

While the latter is more appealing from the perspective of "goodness" of 
the test suite, and ought to be done eventually, on the other hand it is 
somewhat "cosmetic".  I would like to think that, for now, we can live with 
the former for CR interoperability purposes ("two pass").

Thoughts?

That's a thought.

Unfortunately, two of the implementors won't be there (unless we invited 
them, which from QAWG experience is apparently legitimate for a "public" 
group;  or maybe we could get a block of Zakim time and join them in if 
there is need for discussion with them.)

Btw, the reason I objected earlier to a test by test, vender by vender 
verification of all results, as opposed to spot-check or focus on reported 
problematic tests...  Does it make a statement about our view of the 
self-reporting by venders?  Does anyone else in W3C do this?  Do we thereby 
start to establish new criteria for the two-pass convention, "independently 
verified interop data"?    (Plus ... it would dump on Chris about 1000 
individual test claim verifications:  4*250.  I'm sure he wouldn't mind 
that in his spare time  :-)   )
