I have already given feedback on this (see above link) and am supportive  
of the general approach taken with this. I think the core functionality is  
pretty basic -- external subtitles/captions are displayed together with  
the video. The points that seem most important to me to work out at this  
point are:

* DOM interfaces. These should be the same regardless of source  
(external/internal) and format. I also believe these ranges have event  
listeners, so as to replace the cue ranges interface.

* Security. What restrictions should apply for cross-origin loading?

* Complexity. There is no limit to the complexity one could argue for  
(bouncing ball multi-color karaoke with fan translations/annotations  
anyone?). We should accept that some use cases will require creative use  
of scripts/SVG/etc and not even try to solve them up-front. Draw a line  
and stick to it.
