tts:rubyAlign application

Hi all,

It looks like tts:rubyAlign only applies to ruby container, from a style
resolution standpoint, but controls the alignment of all children ruby text
of the ruby container.

In other words, in the following two snippets:

<span tts:ruby="container" tts:rubyAlign="spaceAround">
 <span tts:ruby="baseContainer"><span tts:ruby="base">東南</span></span>
 <span tts:ruby="textContainer" tts:rubyAlign="center"><span
tts:ruby="text">とうなん</span></span>
 <span tts:ruby="textContainer" tts:rubyAlign="center"><span
tts:ruby="text">たつみ</span></span>
</span

<span tts:ruby="container" tts:rubyAlign="spaceAround">
 <span tts:ruby="base">東南</span>
 <span tts:ruby="text" tts:rubyAlign="center">とうなん</span>
</span

the alignment of the two ruby texts will be "spaceAround".

Is that correct?

Thanks,
