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

[Christer Holmberg <[e-mail]>]

Hi,

If this work is adopted I think there should be a discussion e.g., with MMUSIC whether the registration of a new media-type for this is the correct way, instead of using e.g., "application" (or even "data"). There should be some justification for using a new media type.

Regards,

Christer
