TTML2 wide review comment: styling

The styling model used in TTML2 is not CSS and is not processable by a processor/rendering-engine designed to support HTML/CSS.  This leads to complex ‘come from’ process deep in rendering engines, where the behavior has to be dependent on whether the text ‘came from’ an HTML/CSS context or a TTML context.

Please consider adopting CSS as-is, without embellishment or improvement.
