ISSUE-299: dur must be greater than zero

zero duration

dur must be greater than zero

State:
CLOSED
Product:
TTML 1.0
Raised by:
Glenn Adams
Opened on:
2013-12-26
Description:
TTML1SE (and TTML2) refer to SMIL semantics for the dur attribute, and SMIL specifies that dur must be greater than zero. [1] Although this constraint is implied by the reference to SMIL, it would be better to explicitly repeat this constraint in TTML normative text.
