Just an update on this.

I'm proposing that TTML change the default so that text decorations 
(such as ruby and overline, and text emphasis marks in Chinese text 
embedded in Mongolian) appear by default to the right of the vertical 
mongolian line, and underlines appear to the left.

I didn't receive any examples, so i the case as best i could, and it 
seems a decision will be made soon by the TTML Working Group. I'm not 
sure that it will go in Mongolian's favour at this point, ie. it may be 
that any time you want to use Mongolian subtitling you would have to 
override the default position for these things first.

If you'd like to contribute comments or examples, i think you'll need to 
do so before Thursday.

here is the relevant TTML github issue:
