Application of ruby align.

[skynavga]

For the sake of consistency, remove the text "only if the computed value of tts:ruby is container" from the applies to entry of the property definition table for tts:rubyAlign. Moreover, make clear (in prose) that the semantics of application is the empty set for spans for which the tts:ruby attribute's computed value is not container.

I think this change would make the specification worse. I would prioritise usefulness over editorial consistency, here. If we do want editorial consistency I would prefer to introduce similar phrasing for other style attributes where the set of "applies to" elements is a subset of span elements and not all of them.

This is as per the discussion in last week's meeting documented at https://www.w3.org/2019/05/23-tt-minutes.html#item05

Closing, with no further action considered necessary at this time.
