[Bug 12564] This, for me is definately the way to go with text tracks. Since the text is embedded in the media file "In-Band" it means the content never gets lost. This is how we treat audio with video and is how DVD treated text too. Some devices such as iOS may not

Having text tracks separate is also useful, in particular:
* if you are trying to index a lot of videos by their text tracks and just want
to download the text, not the extensive video data,
* if you are auto-translating a text track,
* if you are keeping the text in a DB on the server and serving it with two or
three different video formats,
* if you have a large number of translations of the text track and don't want
to always transfer all of the text tracks to the user,
* if you want to provide text services on top of video that is being served by
somebody else (though in this case you need some security mechanism.)

I'm sure I have forgotten a few further user cases.

The issue is: both external and in-band text tracks are useful and appear in
the wild, so HTML supports both. There is no need to restrict
users/authors/publishers to a single means of doing things.
