The edit of ttp:markerMode with the value "continuous" implies that all time expression in markerMode "continuous" are "labeled synchronization events (markers)". I have two questions with the reference to the last example on the discussion page on issue 151 (http://www.w3.org/wiki/TTML/Issue151Discussion): <p region='r' begin='00:00:27:00' end='00:00:38:00'> <span begin='00:00:28:00'>A</span> <span begin='00:00:29:00'>B</span> <span begin='00:00:30:00'>C</span> </p> Assumption: timebase = "smpte" + markerMode = "continuous" 1) Are the time expressions of the span elements valid? 2) Is the begin of the first span element timed when some external synchronization context emits the event "00:00:28:00" or is it timed 28s after the begin of the parent p (so at "00:00:55:00")?
