ISSUE-262: tts:extent semantics if value not supported

tts:extent semantics if value not supported

State:

CLOSED

Product:

TTML2

Raised by:

Glenn Adams

Opened on:

2013-07-11

Description:

Originally raised by Mike Dolan in Issue-180, the current text (8.2.7) states:

"If a specified value of this attribute is not supported, then a presentation processor must interpret the attribute as if the value auto were specified."

What if the value not supported is "auto"? What does it mean to say that a value is not supported?
