The <track> element points to timed text, i.e. to a file that provides
text fragments along the timeline of the video. SVG is not suitable
for that use. Just like you cannot put a SVG into a <audio> or <video>
element, you won't be able to put a SVG into a <track> element.

However, we can e.g. create a WebVTT file with data in the cues that
point to SVG files or whatever else we want to time-align with the
video and link that in the <track> @src with @kind=metadata.

Cheers,
Silvia.
