Re: [AVTCORE] draft-hsyang-avtcore-rtp-haptics-02: Needs to register "haptics" as an SDP <media>

[Jonathan Lennox <[e-mail]>]

That should be fine, but the specific issue I’m raising is a different one — the SDP media parameters registry at https://www.iana.org/assignments/sdp-parameters/sdp-parameters.xhtml#sdp-parameters-1 is separate IANA registry from the top-level media types registry.  The values registered as SDP media parameters are a subset of the top-level media types, but not all top-level media types are defined for SDP.

Thus, you'll register “haptics” in this SDP registry as well.  I don’t think this should be controversial in any way, since all the hard work has already been done defining “haptics” as the top-level media type.

That is why we modified the draft to update the HMPG subtype registration with IANA (in section 6) and refer to the mediaman draft.
