Correct. Unlike ICE (where we also had a discussion in RTCWEB regarding what to reference), 4566bis does not (Paul, please correct me if I'm wrong) provide new or modified functionality where implementations would act differently based on which spec is implemented.

To be fair, this is mostly a cosmetic thing. We have been working for too-many-years to get the RTCWEB stuff/dependencies done, and the same day as we finally publish the RFCs we immediately end up referencing an obsolete specification :)

 So, as this should not have any technical impacts, I am not going to push for it. I thought it would be an easy thing to do, and wanted to know what people think, but unless someone can come up with some technical issues with referencing RFC 4566 I am also fine leaving things as they are.

Regards,
 
Christer

Hi,
 
Some of the drafts in Cluster 238 that reference RFC 4566, while other reference draft-4566bis-
 
Since draft-4566bis is also part of Cluster 238, and is in the RFC editor’s queue, should we update the references to draft-4566bis? 
 
The change would be done *at least* to the following drafts (I will only check the ones I author/co-author):
 
MMUSIC WG:
 
draft-ietf-mmusic-dtls-sdp
draft-ietf-mmusic-sdp-bundle-negotiation
draft-ietf-mmusic-sctp-sdp
 
BFCPbis:
 
draft-ietf-bfcpbis-rfc4583bis-27
 
One of the reason many drafts do not reference 4566bis is because the drafts were going to be finalized long before 4566bis. But, as that is now not the case….
 
draft-ietf-mmusic-mux-attributes references both 4566 (normative) and 4566bis (informative). In my opinion we could make 4566bis normative there, but I’d like to hear what Suhas thinks.
 
Regards,
 
Christer
