Thanks, but now I am lost. Why is this a 'video' stream and not a 'text' stream, then?

Other characteristics of text are that spell-checking and translation to a different language are reasonable things to do with it. Whether the text/* top level type is like that is another matter again, of course; that type having sufficient problems that it should really not be used for anything much beyond text/plain; charset=us-ascii.

Without that constraint I would have been pushing for this NF> to go under video from the beginning. Timed text, because of its time dependent nature, is an arguable fit for video (but something of a stretch). There is probably a need for a more reasonably defined top level type, like textual/* or something, but the timescales and amount of effort to establish such a thing are non-negligible. -- Chris Lilley mailto:chris@w3.org Chair, W3C SVG Working Group W3C Graphics Activity Lead
