palemieux has just created a new issue for https://github.com/w3c/imsc: == Improve itts:forcedDisplay description == >From an implementer: > i was having trouble parsing the indicated text from the specification: > "If and only if the value of displayForcedOnlyMode is "true", 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." > the following being the dilemma - in the above case, layout is affected in the sense that the invisible content element counts towards presentation (tts:visibility?) OR it is affected in the sense that it is not considered for presentation (tts:display?) Proposed amended text: _If and only if the value of displayForcedOnlyMode is "true", a content element with a itts:forcedDisplay computed value of "false" shall not produce any visible rendering, regardless of the computed value of tts:visibility._ _The itts:forcedDisplay attribute has no affect on content layout or composition, but merely determines whether composed content is visible or not._ This follows the prose of `tts:visibility` in TTML1.
