Why do you > believe otherwise? Because it doesn't actually say that anywhere that I can see, for one, and specifically, the @kind value of metadata remains completely undefined today. Can you point to where kind="metadata" is defined as time-stamped content only? If metadata does not require being timed content (what would that even look like?), then this refutes the assertion that all <track>s MUST be time-stamped. Finally, if we really wanted to play semantic games, I could use TTML with role="transcript", and off I go. This is an artificial restriction (IMHO) and is not a good reason to not continuing to pursue the use of <track>. FWIW, there were a number of other engineers in the room while this discussion was had, including many with more than a passing knowledge of video and media on the web(*), and the "timed text only" argument did not seem to hold much credence with them either. I respect your opinion here, but it is but one opinion, and I have not been convinced that it is totally correct. (* Frank Olivier & Adrian Bateman from Microsoft, David Dorwin & Aaron Colwell from Google, Bob Lund from Cable Labs, Mark Vickers from Comcast, Yosuke Funahashi from Tomo-Digi, and Cynthia Shelley was able to have a brief on-line chat with Sean Hayes who also supported using <track> in this fashion) > > Overloading track is not the right thing to do from a data structure.

Re-use is a common language and design pattern, and has some significant value, especially in the area of author education, where using <track> as the vehicle for adding all textual support files to the <video> element is elegant, is easy to explain, understand and hand-author, and adopts itself to easy implementation in WYSIWYG editors. No technical reason has been brought forward to prove that this is not a viable path forward. Besides, as Jonas Sicking has previously noted, this is software, we can do anything. (http://lists.w3.org/Archives/Public/public-html/2011Mar/0627.html). Silvia, at this time I think that options are starting to narrow, and time is running out. If you have another suggestion please do bring it forward, but I for one (and I will be bold enough to channel other members of the accessibility community) reject outright deferring this to HTML.next; I also reject that a linkage to transcripts *MUST* only be rendered as on-screen text. I have no appetite to make this a longdesc-by-proxy discussion, but in 2012 insisting that an on-screen text link as the ONLY method to link a transcript (the IDREF proposal) simply does not hold water, sorry. It shows a particular lack of creativity and narrow-mindedness that I find hard to accept. JF
