Thank you very much for the review, Meral.

Hadriel - any thoughts on these comments? And Meral, which part of 3261 section 
8.1.1.6 are you thinking that is violated? The MUST? The SHOULD? The should? I 
thought it violated only the SHOULD and should parts… which I think should be 
fine… but looking at Hadriel for confirmation...
