When cues are of kind captions, subtitles, chapters or descriptions, some kind
of rendering is expected, see
http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#attr-track-kind
.

The only kind of cue that is not rendered is of metadata. For that reason,
kind=metadata is appropriate for DataCues which are per definition not
rendered.

If we allowed DataCue to be on a caption track, for example, we'd need to
define a rendering algorithm - likely the content of the text attribute being
rendered verbatim on screen. Is there a use case for that?
