Such as at 
<http://tools.ietf.org/wg/http/draft-ietf-http-v11-spec-rev/>? (Thanks 
thanks thanks to the IETF tool team for the good work!).

I would think that in general the spec talks about HTTP/1.1, and if it 
wants to talk about future versions, it has to specifically do so.

So the original problem seems to be that the spec defines the complete 
set of hop-by-hop headers, and then talks about not defined above. Maybe 
the text needs to be expanded to something like:

	Future revisions of the HTTP/1.1 specification and later
	versions of HTTP MAY introduce new hop-by-hop headers. Those
	headers MUST be listed in a Connection header (Section 14.10)
	for backwards compatibility with this specification.

Best regards, Julian
