Yeah, I don't think arguing about it between secdir reviewers
will help us so much:-)

I noted that this had been raised in my ballot ([1] at the end)
and asked if text is needed. Randy - if you have suggested text
that could go in there that'd be good. I'm not clear enough
about the relationship between that attack and this draft to
know what'd be good to be honest.

Cheers,
S.
