Silvia can provide further feedback; however, it you take a look at [1],
 you can see that the IDL definition of TextTrackCue has been made
identical to the definition in [2]. That resolved the fork between the two
specs regarding this interface definition.

In addition, a new DataCue interface was defined at [3], containing both a
binary and a text data accessor, which meets the needs of exposing in-band
@kind metadata tracks. This satisfies the known use cases for exposing such
content (as far as I'm aware).

Finally, the text attribute was just restored to VTTCue today in [4], which
restores the raw text getter/setter for VTT cue instances.

Overall, I'm satisfied with these changes and feel it is the right way to
