So:

1. the XML escaping stuff has been OK'd. (Nicolas, Anton)
2. The err_recognition change has been OK'd (Anton, James on IRC)
3. Multiple nice review passes have been had with the actual encoder
and muxer, and the requests have been applied.
4. The document generated in the FATE test actually passes validation
in https://github.com/skynav/ttt .

Thus, I will be pulling this set in Soon (probably tomorrow). Thus if
anyone still wishes to have a say, I recommend doing it earlier than
later. Then I will be moving onto the TTML-in-MP4 work, which I have
been able to refactor onto relatively working state earlier this week
:) .
