The property for specifying the size of ruby text is 'font-size'.
Saying anything else needs to be approved by the WG (and I think
will get rejected, it makes no sense).

We had a suggested default UA style sheet that specified the size
of ruby text at 50% of the base text.

This was all very clearly specified, and writing anything else about
the font size is not a "clarification", it's a very significant change.

If we need to add a new automagic keyword to 'font-size' to handle
ruby, we can bring that up for consideration. But adding a paragraph
saying the font size is UA-dependent is IMHO not the right approach.
