JEPA published "Minimal requirements on EPUB for Japanese Text Layout", edited by me. Basically, it references to the W3C note and list 14 requirements. This document can be seen as a minimal requirement document on CSS. http://www.jepa.or.jp/press_release/reqEPUBJ.html Then, Murakami-san prepared a sketch of EPUB extensions for supporting the minimal requirements. It is written in Japanese. Again, it can be seen as an extension proposal to CSS. http://nadita.com/murakami/epub/epub_JapaneseTextLayout_ja.html Most of the added mechanisms in this document are logical properties and values. The other mechanisms are ruby and bouten (text-emphasis). On top of such mechanisms, this document provides some advice to implementors. I do not think that they have to be standardized. Rather, they should be left to implementors, just like neither CSS nor HTML mentions rivers in Western typography. I am aware of some other minor issues about vertical writing. - Automatic numbering of itemized list including tate-chuu-kyo numbers (I learned this from Murakami-san) - "odd-page" (not "right) as the value of page-break-before for both vertical and horizontal writing (Again, I learned this from Murakami-san) - A section title as the last line is acceptable in vertical writing if the section title appears in the right page of a folio. Cheers, Makoto
