No preference for date, meet on any two days. Flexible about days. Joint meeting with CSS WG and with Web and TV IG. Avoid overlap with Web and TV IG. Permit observers. Not member confidential. Estimate ~6 attending technical plenary. Estimate ~3 attending AC sessions Tuesday and Thursday. https://www.w3.org/2017/11/TPAC/Overview.html Chair was asked for further clarification about the joint meetings and the overlap avoidance; since Web and TV IG are likely to meet on the Monday, and CSSWG on the Monday and Tuesday, I requested Thursday and Friday for the main TTWG meetings with joint agenda slots with the other two groups on Monday and/or Tuesday.

See this summary of the discussion<https://lists.w3.org/Archives/Public/public-tt/2017Jul/0062.html>. Hopefully we can request that work begins in CSS to support the subtitle and caption requirements we have identified in TTML2 that currently have no support in CSS, during next week's CSSWG meeting in Paris.

At the moment of writing this agenda, there are: TTML1 issues: * 3 open issues with no milestone, none marked as discussed and agreed * 37 open issues in "3rd Ed" milestone, 15 marked as discussed and agreed * 11 open issues in "3rd Ed Test Suite" milestone, none marked as discussed and agreed TTML2 issues: * 2 open issues on the Editor's WR Work List milestone, 1 of which has a PR (#397); * 52 open issues with no milestone, none of which has a PR open label. * 7 open issues awaiting some feedback on disposition, which are in the "Group's WR action required list" milestone, including #316 which is to review the deprecations before finalising the WR.

Issues Iterate through open issues with no PR – decide action to take on each, e.g. defer to CR, defer to TTML.next, close etc. If there are any issues that we decide need to be resolved before WR a proposal for the fix is needed ASAP (basically, it's too late already unless it can easily be agreed by the group).
