ISSUE-453 (forcedDisplay intro text): Clarify relation between forcedDisplay and visibility in intro statement [TTML IMSC 1.0]

http://www.w3.org/AudioVideo/TT/tracker/issues/453

Raised by: Nigel Megitt
On product: TTML IMSC 1.0

The introductory text to itts:forcedDisplay is currently:

"itts:forcedDisplay allows the processor to override the computed value of tts:visibility attribute in conjunction with an application parameter displayForcedOnlyMode."

This could easily be misread as saying that the computed value of tts:visibility is actually modified by itts:forcedDisplay, which is not intended, and not what the following normative statements say.

I propose the following replacement introductory paragraph:

itts:forcedDisplay can be used to hide content whose computed value of tts:visibility is "visible" when the processor has been configured to do so via the application parameter displayForcedOnlyMode.


This issue filed as per Action-437.
