I'd like to make this change to Gecko in the very near future, but 
before starting to actually land code it would be good to have 
confirmation of the decision.

My current understanding is that we'll end up with:

   writing-mode: horizontal-tb |
                 vertical-rl | vertical-lr |
                 sideways-rl | sideways-lr


   text-orientation: mixed | upright | sideways (or sideways-rl?)

where text-orientation has no effect in horizontal or sideways-* writing 
modes; it's only applicable to vertical-* modes.

Regarding the 'sideways' value of text-orientation, this (AIUI) is the 
same as the current draft's 'sideways-right', which is already 
implemented in several browsers (with or without prefixes). As such, 
would it be better to retain the 'sideways-right' name, or perhaps to 
accept it as an alias of 'sideways', so as to avoid breaking content 
that is already using that name?

A firm decision on the new design, as well as any guidance on what to do 
with 'text-orientation: sideways-right', would be very welcome. Thanks!
