Comment 7 for bug 114441

Adding Roger Sidje to Cc list. In some ways, Ruby is similar to some of the
things that MathML requires. In Ruby, the main text is in one normal size, and
the Ruby text is smaller and drawn above or below the main text (in the
horizontal case; left or right in the vertical case).

In math, we also have superscripts and subscripts, and various things drawn at
various sizes above and below other things, and so on. It is quite possible
that Roger and the other MathML folks could have some good ideas for Ruby too,
or perhaps whoever implements Ruby could get some ideas from the MathML code.
Then again, Ruby is simpler, and is somewhat similar to a plain table, so
perhaps we don't need anything as complicated as MathML's implementation.
