W3C Japanese Layout Task Force has already published such examples, 
and they are available at 

http://www.w3.org/2007/02/japanese-layout/20071108/kihonhanmen-examples.pdf

This document shows seven examples.  The first one is single column,
vertical writing.  Page 2 shows input parameters, some of which require new 
elements or attributes.  Page 4 shows margins computed from these 
input parameters, where such margins can be represented by OOXML 
as of now.  Page 3 shows a page image.  The other examples are also 
described similarily.

Sure.  I will speak with people in the task force and the Japanese SC34
mirror.

Cheers,
Makoto
