Prioritise discussion for this meeting and look ahead

Check-point for order of topics and any other business.

Note I did not raise w3c/tt-profile-registry#71 on this agenda because I suspect that we will not have all of @mikedo, @cconcolato and @skynavga on the call - if that suspicion is wrong, we will try to cover that long-standing issue.

IMSC1.2

APA WG Horizontal Review comments

Progress report from @nigelmegitt on making a plan with APA on how to resolve the open issues.

ARIB incoming liaison

The issues have now been raised as separate GitHub issues, which we should iterate through over the coming weeks as time allows:

[WR/ARIB] Mixture of text and image w3c/imsc#543

[WR/ARIB] Character Sets w3c/imsc#544

[WR/ARIB] (meta) Compatibility with ARIB-TTML w3c/imsc#545

[WR/ARIB] Compatibility with ARIB-TTML / 1. Image handling w3c/imsc#546

[WR/ARIB] Compatibility with ARIB-TTML / 2. Font handling w3c/imsc#547

[WR/ARIB] Compatibility with ARIB-TTML / 3. Animation w3c/imsc#548

[WR/ARIB] Compatibility with ARIB-TTML / 4. Audio presentation w3c/imsc#549

[WR/ARIB] Compatibility with ARIB-TTML / 5. Additional style control w3c/imsc#550

We should work through these before returning to #116 to prepare a liaison response.

TTML2 2nd Edition Implementation Report

Tests

We do not expect to add any more tests to TTML2 Tests after the currently open pull requests at https://github.com/w3c/ttml2-tests/pulls are merged.

Add fragment profile designator tests (w3c/ttml2-tests#231). w3c/ttml2-tests#235

Placeholder for follow-up on last week's discussion, if needed.

Implementation Report

Status of this? Does it reflect the test suite changes? @cconcolato volunteered to update it with the tests as we expect them to be.
