Disagreed, otherwise I obviously wouldn't have had to escalate it.

The original bug was about two things 
(<http://www.w3.org/Bugs/Public/show_bug.cgi?id=7806#c1>):

For question 1) you gave an answer to that I wasn't satisfied with. 
That's "discussing", not "resolving".

For question 2) you added a SHOULD wrt stability. So previously it was 
silent on this (bad!), but now it says that you can ignore the 
requirement in certain cases (bad in a different way).

Best regards, Julian
