Yes, please -- I'm implementing this in gecko right now, so 
clarification on this would be really useful.

And I agree with Koji here: I don't think 'sideways-rl' is good as a 
'text-orientation' value. This property is distinct from 'writing-mode' 
and it's better not to confuse the values of the two.

So my preference is still the simple 'sideways', with the alias 
'sideways-right' supported for backward compatibility (option B above).
