palemieux has just created a new issue for https://github.com/w3c/ttml2: == condition="forced" does not match the behavior of itts:forcedDisplay == TTML2 states: > For the purpose of presentation processing, if an element specifies a condition attribute, and the its <condition> expression value evaluates to false, then the semantics of the element and its descendant elements must be ignored unless explicitly specified otherwise. In contrast, IMSC1 states: > a content element with a itts:forcedDisplay computed value of "false" shall not produce any visible rendering, but still affect layout, regardless of the computed value of tts:visibility. It is therefore not possible to achieve the `itts:forcedDisplay` using `condition="forced"`. Please view or discuss this issue at https://github.com/w3c/ttml2/issues/482 using your GitHub account
