mike: caution here: not sure if the problems are the same here.

[on Philippe Le Hégaret - due 2013-11-07].
Draft charter
Nigel: that's a standing agenda item
... a few points to note
... initial chairs is one
... idea is that I would become the other co-chair with David
... taking care of the TTML part
... that's the draft plan
<nigel> [35]http://www.w3.org/2013/10/timed-text-charter.html
[35] http://www.w3.org/2013/10/timed-text-charter.html
Nigel: some wording in the deliverables
... on live production streaming
... not precise enough
... will come up with a proposal
... milestones
... quite a lot of crunch
... coming at the same time
... TTML 2.0 and IMSC might need to be revised
pal: real need for ttml 2 and imsc and I think we can do both
... so no reason to have different timeframe
... imsc relies on ttml 2
... so imsc at best can happen on the same time scale
nigel: it seems safer to put a bit of offset
pal: we have a draft for imsc
... I hope we won't pushback ttml 2 further
... no significant issues against imsc
... so pretty confident with the timeline
nigel: alright
... on dependencies, we don't have one on XML
<nigel> nigel: similarly on Internationalisation
