Agenda+ F2F

We have a tentative proposal to hold a F2F in the week before NAB – NAB runs 11-16 April, so we're looking at for example 9-10 April. A couple of people were going to look at options for this – if we're going ahead we need to confirm soon.

Agenda+ Issues

Our key task today is to process any outstanding review points on the TTML2 FPWD snapshot [2] and proceed to a version that we can publish. We may need to go ahead with some issues remaining open.

Note that the following are not in the FPWD snapshot, but have been discussed - we may wish to process some changes into the snapshot for the FPWD:
Issue-224 edits (stereoscopy);
the new names for tts:width and tts:height discussed on the reflector (related to Issue-236 and letter spacing);
Issue-231, Issue-229 and Issue-219 tts:textCombine edits.
