For record, rather than repetition, I will respond in this thread only 
when I will see some new argument. What's been said is not acceptable to 
me and I stay in strong opposition of architecture draft (including 
John's recent PR).

If you carefully see the name of the draft [fossati-09], it was intended 
for TLS WG and not RATS WG. TLS WG was already informed about it in 
February [1].
