One more thing that I just realised: sometimes it is very obvious that a
description cue will not fit into a given time frame - in particular if there
isn't actually any time available to put it in and it is basically associated
with a time point rather than a segment.

In this case, it would be possible to record into the WebSRT file the requested
pause duration for the screenreader for the cue and have the player pause for
that duration as it reaches the cue. This solution is based on heuristics as to
how long an average screenreader will take to finish reading a cue and can turn
out rather inaccurate, but it allows solving the situation without having to
wait for an event from the screenreader to stop / continue playback.

Actually, this is the way in which I will be implementing this functionality in
a JavaScript demo for now, which of course means introducing a non-standard
marker into WebSRT. Gah, damned custom extensions... :-(
