IMSC vNext requirements window

As discussed in #117 the window for IMSC vNext requirements is now open. Placeholder agenda item for discussing closing date, scope etc.

ARIB incoming liaison

The ARIB 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

We discussed this at length in #117, so we may skip it this time.

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

Proposal is in IMSC vNext to reference the ARIB set for "ja" language.

[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.
