Hello CSS-WG,

Professor Kobayashi, participating in Keio University's
Advanced Publishing Laboratory[1], has written a memo
about how to layout ruby in Japanese, to share with the
CSS-WG, hoping it would be useful for our work.

This is a simple approach, focused on getting the defaults
right, rather than on offering lots of options. In a way,
this is a complement to JLReq: while JLReq describes all
the variants that may be encountered, this describes what
you should do in the typical case.

I think this is an interesting read on its own, and that
it may help us answer some of the open issues in the
css-ruby spec, or identify some desirable improvements.

I expect this will eventually be submitted via the i18n-WG,
but for now, I have made an English translation available
from here:


I'll give a brief introduction about this during our F2F
in Berlin next week.

If anyone has questions, I will be happy to translate and
relay them to Professor Kobayashi, or to answer the easy
ones myself.
