Certainly. Also, I would expect any code to be bracketed with

#if ENABLE(VIDEO_TRACK) && ENABLE(TTML)
#endif

> I am not sure that the WebKit community will be interested in having an implementation of TTML, particularly given the dependency on the XSL-FO formatting model.

(1) the use of XSL-FO in the TTML spec is only for explanatory purposes, namely, describing formatting semantics, and not used for implementation purposes; the same semantics can be restated in terms of CSS as well; so that is not really a substantive objection;

(2) IE10 implements support for a subset of TTML;

(3) the FCC rules could translate to mandatory support in a variety of deployment contexts, e.g., HTML5 UAs embedded in television devices available at retail that are already subject to a variety of FCC rules;
