I was not aware of draft-saintandre-xdash when I wrote this draft.
It seems appropriate to include a reference to this.
As draft-saintandre-xdash is only a draft yet, how can I update
draft-petersson-forwarded-for to take this x- deprecation into account?
Suggested formulations are welcome.

If the from field should be specified in this draft, which might be a
good idea, I think the value should be specified to refer to
http://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-16#section-9.3
or RFC2616 section 14.22.

I don't see the usecase for it, containing an URN.
More important, I don't think it
would be appropriate to divert the semantics, or syntax of the field
from the definition in RFC2616 / draft-ietf-httpbis-p2-semantics.
