Hi all,

TTML allows both 'lrtb' and 'rltb' as values for writingMode, and
references Section 7.29.7 at XSL.

CSS Writing Modes Level 3 [1] states that both 'lr-tb' and 'rl-tb' (as
defined in SVG) are both replaced by 'horizontal-tb'.

Why would 'lr-tb' and 'rl-tb' be redundant?

Thanks,

-- Pierre
