The text for MPEG-2 TS looks good but there is one thing missing that had been
suggested.

As it stands in the proposed text, when the in-band metadata track dispatch
type is set, there is nothing to indicate if the text track was from an MPEG-2
TS, Ogg, WebM MEPG-4 media resource and script won't know how to interpret the
attribute. One way to fix this would be have inBandMetadatTrackDispatchType
start with "mp2t-", "ogg-", "webm-" or "mp4-". For example,

If the media resource is an Ogg file
The text track in-band metadata track dispatch type must be set to _the
concatenation of "ogg-" and_ the value of the Name header field.
