Sorry for the list-spam.

One more thing: If we call TextTrack's addCue() method with a DataCue, and the TextTrack's kind isn't "metadata", we're not supposed to add it. Do or do we not remove the cue from any existing tracks?<BR>
<BR>
Here's a concrete example:<BR>
<BLOCKQUOTE TYPE=CITE>
video = document.createElement("video")<BR>
goodtrack = video.addTextTrack("metadata")<BR>
badtrack = video.addTextTrack("subtitles")<BR>
cue = new DataCue(1, 2, null)<BR>
goodtrack.addCue(cue)<BR>
badtrack.addCue(cue)<BR>
</BLOCKQUOTE>
Now is goodtrack.cues.length 0 or 1?<BR>
<BR>
It seems to me that what we should do is check if the track's kind is "metadata" before following any of the other addCue() steps, which would mean in my example above, the answer would be 1.<BR>
