Liaison, Issue-309 discussion, Issue-312 edits

 

Agenda+ Prioritise discussion for this meeting

 

Check-point for order of topics – I'd suggest:

1. MIME codecs parameter if we're quorate on this topic

2. Actions,

3. Issues - pending review first, then open and discussed, then raised

4. Planning for next change proposals to work on

5. AOB

 

Agenda+ MPEG liaison re MIME Codecs parameter

 

This is scheduled for a major discussion for this topic since all main
contributors will hopefully attend.
