Re: [TLS] comment on null encryption ciphersuite; https RFC amendment ...to compensate

Peter:

1. TLS has always included NULL cipher suites. They are in RFC 2246.
2. The IESG has already approved this document. It's in the 
   RFC Editor queue.
3. I think the current security considerations text is clear and 
   yours doesn't seem to to substantially improve matters.

That incongruity aside, we can address my objection by listing - as inappropirate - those financial data -related account data types that I enumerate.
