[Ballot discuss]
While I agree with the motivation behind this document, I have a couple of minor concerns about how the new Media Feature Tag is defined:

In Section 3:

  The 'sip.app-subtype' media feature tag is of type token with a case-
  sensitive equality relationship.

Why is equality case-sensitive? RFC 2045 is quite clear that MIME subtypes are case insensitive, see Section 5.1 of RFC 2045.

If you really want this to be case sensitive, you need to define which case is valid. For example RFC 2913 defines that only lowercased version is used.

  Its value can be any registered or private MIME application sub-type.

I think you need a pointer to RFC 4288 (and it should be a normative reference), Section 4.2. And please point to "subtype-name" ABNF production.


6.  IANA Considerations

  Values appropriate for use with this feature tag:  Token.

I think this should be "Token (equality relationship)", as per RFC 2506.
