The design of the Text Track API and WebVTT had people involved from
all corners of the caption universe, so this is the outcome of work of
multiple people. If you don't feel you should be included in that
"we", you are free to interpret it as "they".

I am grateful that you have forwarded the proposal to the TTWG. I was
simply waiting to hear feedback from other fora first, which include
the HTML WG, the WHATWG and the TTCG. Seeing as this design currently
influences the WebVTT spec and the HTML spec, I found these three fora
had to be my first point of call.

I apologize if you take offence at that. It was written to point out
that both TTML and WebVTT are essentially serialisation formats for
cues and that they should each be able to deal with each other's cue
formats. This was not meant to create more controversy, but instead
bridge that controversy.

Might I ask you to take your time to read the proposal properly and
provide me with technical feedback. I would highly appreciated it.

Thanks,
Silvia.
