palemieux has just created a new issue for https://github.com/w3c/ttml2:

== Incorrect implicit begin value ==
The following is incorrect: in the case of a child of a sequential container, the implicit begin time is equal to the desired end time of the previous sibling, or the desired begin time of the parent if no previous sibling exists.

>As defined by [SMIL 3.0], ยง 5.4.3, if no begin attribute is explicitly specified on a timed element, then a default (implicit) value is determined by the nearest time container ancestor; however, in TTML, that ancestor is either a parallel time container or a sequential time container, both of which apply a default value of 0.

Suggest referring to SMIL, and not elaborating.
