ISSUE-453: Clarify relation between forcedDisplay and visibility in intro statement

forcedDisplay intro text

Clarify relation between forcedDisplay and visibility in intro statement

State:
CLOSED
Product:
TTML IMSC 1.0
Raised by:
Nigel Megitt
Opened on:
2015-10-16
Description:
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.
