One thing we forgot to mention; we have introduced a new terminology, "horizontal/vertical typographic mode" in the text-orientation property[1].

The idea is that, when text is graphically rotated by 90 degrees, even though it is layout in vertical, its typographic characteristics are still the same as horizontal text flow, and we want to distinguish this from vertical text flow for Japanese/Chinese.

Some typographic features such as underline are affected by the typographic mode, not by the physical flow of characters. We have updated the text-underline-position property[2] in CSS3 Text to reflect this terminology change.

Subject: [css3-writing-modes] New Working Draft: CSS Writing Modes Module Level 3

Last week W3C published the second draft of CSS Writing Modes Module Level 3.
This module covers bidirectional and vertical text. Major changes since the last draft include an editorial overhaul, more details on the interaction of orthogonal flows, changes in requirements for horizontal-in-vertical feature, and some other minor tweaks to how things interact; no syntax was added or changed.

As always, please send comment to this mailing list, <www-style@w3.org>.
