in issue 8, I propose:
(Look in the edited draft -06g that I attached some days ago for how
the proposal appears in the text )
------------------------------------------------------------------------------------------------------------
8. Include more fields for attribute registration from 4566bis
Section 6 has the form for attribute registration by IANA. There are a
couple of fields missing that will be important for use of the
specification in the WebRTC environment. Include these fields if that
is allowable according to current IANA procedures and if that does not
delay the publication of this draft. These fields are needed for use
of text media in WebRTC.
Change:
In two locations from:
"Usage Level: media"
to:
"Usage Level: media, dcsa(subprotocol)"
Insert in two locations in the registration forms:
"Mux Category: NORMAL"
---------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------
I checked in current IANA registrations, and found that all SDP
attribute registrations now include the "Mux Category".
So, I assume that we are obliged to do so also and hope that we can
agree on that.
As far as I understand the logic, we should specify NORMAL.
I saw no trace yet of registrations of "Usage Level: dcsa(subprotocol)"
I would like to get advice from someone with insight in the SDP
attribute registration and the status of the dsca(subprotocol) value
on how we should proceed in order to get the dsca(subprotocol)
included in a smooth way without causing exessive delay.
I found in
https://tools.ietf.org/html/draft-ietf-mmusic-data-channel-sdpneg-11#section-8.3
that the registration of dcsa(subprotocol) seems to require a specific
actual subprotocol. That is further away in time, and if that conclusion
is right, we need to include MUX Category but exclude "Usage Level:
dcsa(subprotocol)" from the registration.

Gunnar
