The document summarizes requirements for the EPUB Working Group on EPUB Global Language Support (EGLS). It lists various requirements submitted by members regarding features like page progression direction, writing mode, mixed text, line breaking, ruby, and user-defined characters. The requirements cover languages like Hebrew, Arabic, Korean, and features for manga. They need to be unified, reviewed by the working group, and will be frozen in October after the first public working draft is published. Not all requirements are guaranteed to be satisfied.

- 13. EGLS_MM_06 Stylesheets for more than one principal text directionThe design of CSS2 hinders this requirement. Typically, vertical writing HTML documents (such as this example HTML document) for one principal text direction only.Note: Really good layout can be achieved only when both contents and stylesheets are dedicated to one particular principal text direction. However, switching should not lead to unreasonable layouts.EPUB WG/EGLS Sub-group132010/8/3

Readers may not need the ruby, but concern the continuity of content. Students could choose to have RUBY displayed while learning ZhuyinFuhao. Readers could choose to have RUBY displayed via hidden ruby or pop-up screen. EPUB WG/EGLS Sub-group292010/8/3
