Oh, in my recollection the rule *2. below was discussed as one of the
approaches and dismissed in favor of the sticky role. Therefore the
closing email [1] seems to be wrong.

The IRC log seems to support me in this (I don't think I'm posting any
member-confidential info here):


08:38:59 <scribe> Proposal (again): Define a new role. Characteristics
of this role are; 1. if you process a Rep header targetted at this role,
you MUST resinsert it.
...
08:42:55 <scribe> Noah: We should say that it's OK for two
Representation headers in a message to have the same URI and role
08:43:34 <scribe> Noah: I'd rather add a note saying that such headers
would typically have different media types
08:43:50 <scribe> s/media types/metadata
08:44:34 <noah> s/metadata/metadata such as media type/ :-)
...
08:50:54 <scribe> Proposal for resolving 455: Define a new role as
above. Add the two statements above concerning two representation
headers and the note about metadata. Add text stating that
implementations might need to process Rep headers before other headers
that might deref URIs
08:51:59 <scribe> Issue resolved with above resolution without objection
