ISSUE-424: Awkward text re: smpte:backgroundImage dimensions

Awkward text re: smpte:backgroundImage dimensions

State:
CLOSED
Product:
TTML IMSC 1.0
Raised by:
Glenn Adams
Opened on:
2015-09-21
Description:
"the width and height of the region extent associated with the div element shall be specified and shall be equal to the width and height of the image source referenced by smpte:backgroundImage;"

IIUC, this should be written as follows:

"the width and height of the image source referenced by smpte:backgroundImage shall be equal to width and height of the extent of the region in which the div element is presented;"

Note that this places the requirement on the image geometry and not on the div element. Also, this needs normative language regarding what to do in case this constraint is violated by the image geometry.

As indicated in the conformance section, the specification does not specify processor behavior in the presence of non-conformant documents.

Then perhaps informative advice could be provided.

[nigel]: [Meeting 2015-10-15] Agreed to close since no wording for non-conformance handling has been proposed, by anyone.
