Re: HTTPbis -10 drafts published : Connection header

just to belabour the point

RFC2616 S 14.10

    Message headers listed in the Connection header MUST NOT include end-
    to-end headers, such as Cache-Control.

This should either

a) be removed from HTTPbis if we are to take the approach suggested by 
Roy; or
b) be elaborated further to specify what an agent should do upon 
receiving a message that violates this MUST level requirement

It's pointless compromising the integrity of a perfectly sound specification so that you can club a few idiots over the head with it.  That's a self-defeating principle - the idiots will simply find another dumb thing to do that you couldn't predict.
