DVB has many, many different ways of carrying data in an MPEG-2 transport stream and there's no outright winner or lowest common denominator. If a text track never exposes any cues, we shouldn't expose its existence to browsers. That's like saying: hey, I have some data, but I won't give it to you. Or if we apply that logic to an audio or video stream: it's like announcing that a video stream exists, but not rendering it. Such tracks are not relevant to this specification. Regards, Silvia.
