first results on video accessibility experiments

Hi all,

In recent weeks I have been preparing a specification based on the
original <itext> idea for associating time-aligned text with <video>.

I now have some initial results.

You can check the specification here:
https://wiki.mozilla.org/Accessibility/HTML5_captions

The demo is here: http://www.annodex.net/~silvia/itext/

And a detailed description of the experiment is here:
https://wiki.mozilla.org/Accessibility/Experiment1_feedback

I have received great feedback from Philip Jagenstedt, who is
developing the <video> support at Opera.

I wanted this list to see it before sending it on to WHATWG. If there
is anything that is not comprehensible immediately, please speak up.

Also, I am still trying to figure out what a better specification
would look like. Philip's feedback is excellent, but integrating it is
challenging.

I am particularly looking for feedback on the idea of having an
<itextlist> element to separate between the different categories of
time-aligned text. And for feedback on the javascript API.

Any feedback is very welcome!

Best Regards,
Silvia.
