What about these issues with using an HTML parser:

* Non-browser user agents are likely not going to be happy to include an HTML
parser and ECMAScript engine for something as simple as subtitles. (Assuming
the fragment parser executes <script>, something I assume but haven't checked.)

* 1 document per cue is likely significant memory overhead. Is 1 document per
cue actually necessary, or just something that was suggested at some point?

* Things like <img> in cues will either behave erratically, or require complex
logic to load them ahead of time.

* class="philip" and class="henri" doesn't carry the semantics that there are
two different speakers, which would be necessary to allow the user (not author)
to style different speakers differently.
