Proposed change: It should not be interpreted as discouraging the use
of AES-128, nor encouraging the use of AES-192 or AES-256 unless
there is a strong cryptographic reason to do so.

How about "must not" rather than "should not." Yeah, it's not anappropriate use of MUST or SHOULD, but I think the emphasis should bethere (and my use of "should" is also intentional). We need to fightthe slide.


I think Dave's paragraph is wonderful.
