Focus topic(s) for this week

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).


Current open issues: https://github.com/w3c/ttml1/issues and https://github.com/w3c/ttml2/issues

See spreadsheet of editorial actions at https://github.com/w3c/ttml2/blob/master/spec/ednotes.xlsx
