I believe it is very much relevant inasmuch as the text transcript
should also support navigation.

To put it otherwise, the existence of a transcript should not preclude
viewing of the video or auditioning of the audio. It is not a case of
either you consume the media or you consume the transcript. We need to
support both, time aligned.

This is why I don't think the approach of a pointer to the transcript in
a context menu--as an attribute on the main element makes sense. It
doesn't meet the transcript use case, as I understand it.

Perhaps we need to clarify the use case for transcript?
