I'm about to issue a CfC on publishing Selectors as a CR, independent of  
getting the test suite done. Because it has taken a long time not to get  
it done, and the result is no CR.

We will need to agree on a Test Suite, and on exit criteria. So this  
message is to see if there is any disagreement.

A possible question is whether it counts to have a JS implementation or  
similar. I think it would be reasonable, so long as it is a completely  
independent implementation, although I would rather have it *in addition  
to* native implementations in shipping products.

I wonder if we need to make these additional tests rather than baseline,  
for the purposes of demonstrating that browsers get this spec right.

I think that at most we should be designating tests as baseline or  
additional, rather than trying to classify the various kinds of additional  
files.

Maybe, maybe not, as per above.
