Re: mapping between TTML and WebVTT

No. I am not working on a mapping from TTML to WebVTT. And No, I do not
agree to (and would object to) incorporate such a mapping into the TTML2
spec. It can be done in a separate document, although, who would have an
interest in creating such a document, I don't know. I might be persuaded to
do such work if a sponsor stepped forward for such independent work, but
none of my sponsors have expressed such interest.

What I am working on for inclusion in TTML2 is a mapping to CSS/HTML5 as an
additional alternative to the current XSL-FO mapping.
