Is this comment as a Chair, or as an Apple representative?

In my response to Benjamin yesterday, I wrote:

So you are concerned with backward comparability? Would this calm your

     <transcript src="whatever" id="tr1"><a

...essentially a re-use of the <video> pattern: simple, obvious, easy to
both author and explain - the link is the fallback when <transcript> isn't
supported. The IDREF association still goes to the <transcript> container:
in supporting browsers it then would load the transcript inside the
container on the 'button' click. For non-supporting browsers, the
<transcript> element degrades to a non-semantic <div>, and/but the button
click moves focus to that 'div', and the next focus able item is the anchor

The one thing I think that will gain little support is the one which
suggests that access to a transcript can ONLY be achieved by using <a
href="">transcript</a>: d links failed a decade ago, when design esthetics
still tolerated java applets and spinning mailboxes, and will surely meet
equal resistance today. (Arguments that this is what we are getting today
carry little water, as most videos DON'T have transcripts - perhaps because
linking them via text links is ugly...)

Does this address your concern as well?
