<!-- comments --> in particular won't work because --> is already used in  
the timing format:

00:00.000 --> 00:01.000

In any case, coming up with a syntax is not a problem, /* comments */ and  
// comments like CSS/JavaScript are the most obvious choices.

The question is rather if the comments should be exposed as DOM comment  
nodes in getCueAsHTML, which seems to be what you're asking for. That  
would only be possible if comments were only allowed inside the cue text,  
which means that you couldn't comment out entire cues, as such:

00:00.000 --> 00:01.000

00:02.000 --> 00:03.000

00:04.000 --> 00:05.000

Therefore, my thinking is that comments should be removed during parsing  
and not be exposed to any layer above it.
