RE: TTML and aspect ratio

Well, yes, that would be the logical thing for W3C to do in reaction to
SMPTE's request :-)

But that would be a TTML 1.1 enhancement, which may be a bit further out.
Once SDP-US and TTML 1.0 2nd Edition publish, I expect the TTWG to return to
working on 1.1.

I suppose instead you can define your own attribute (TTML allows foreign
namespaces), but that would not be interoperable of course.

We ingest captions from many different formats besides 608 & 708, and thus
need a general way to resolve this issue.  The most obvious being <tt
tts:aspectRatio>.
