-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'd really like to understand how the chairs coming to the conclusion that there was *no consensus* on recommended codecs can result in a draft that includes 3 MUSTs and 1 SHOULD. This draft effectively makes 3 new codecs MTI for a range of devices. I understand that it's an individual draft and you can write whatever you like in there, but it definitely goes against the result of the WG discussion.
