Re: Kicking off to the Text Tracks Community Group

Hi all,

could others also please state what they believe should be in this
first WebVTT specification that we pull from the WHATWG into this CG?

I am particularly keen to hear from the copyright holders on the
WHATWG specification (i.e. Apple, Mozilla, Opera), since it will be
their contribution to this CG that we are talking about. But I'd also
like to hear from the community what their expectation is about what
that document should contain.

Thanks,
Silvia.
