W3C removed the formatting below which makes it hard to read...I switched to Rich Text and put back a few CR’s…

Also, somewhat relevant to ponder, especially if it is affected by whatever we come up with here, is ISO 14496-30, COR1 dealing with TTML aspect ratios:

In the TV application of TTML, consideration should be given to:

SMPTE ST 2016-1:2009 - SMPTE Standard - Format for Active Format Description and Bar Data 

SMPTE ST 2046-1:2009 - SMPTE Standard - Specifications for Safe Action and Safe Title Areas for Television 

SMPTE RP 2046-2:2009 - SMPTE Recommended Practice - For Television – Safe Areas for Protection of Alternate Aspect Ratios 

SMPTE EG 2046-3:2010 - SMPTE Engineering Guideline - Safe Areas for Television

SMPTE standards are available here:
