Identity selection related requirements (Re: [ietf-dkim] RFC2822.Sender)

[william(at)elan.net]

That this thread is being discussed brings up a requirement that policy 
record syntax should be capable of supporting multiple identities.

A subquestion of that is if policy record identity should or should
not be part of the query selection process (i.e. _from._policy if DNS).
That BTW brings up a separate issue about how policy record queries are
to be done, which is a protocol-related requirement and those appear 
to not be mentioned in the requirements document right now.

The question that you're actually discussing in the thread about
'RFC2822.Sender' is is what identit[y|ies] you actually want to
define for initial use and how.
