Not sure what you are asking here, but  we think it likely that we'll need to support both (a) captions 'converted' from 708 (or something like) and also (b) the FCC suggestions, which want the ability to color and scroll windows, etc.  To that end, behaving as if some fixed style-sheet was built-in, that gives (e.g.) access to window colors, would be desirable.
