The CSS WG published a new working draft of "CSS Writing Modes Module 
Level 3":

    http://www.w3.org/TR/2011/WD-css3-writing-modes-20110901/

It contains CSS features to support various international writing modes, 
such as left-to-right (e.g. Latin or Indic), right-to-left (e.g. Hebrew 
or Arabic), bidirectional (e.g. mixed Latin and Arabic) and vertical 
(e.g. Asian scripts).

Major changes since the previous draft include: 

  - Redefined which side of a bidi-broken box's border is drawn.
  - Altered the allowed combinations of ‘unicode-bidi’ values and
    defined ‘plaintext’ to use heuristics for inline elements as well.
  - Renamed ‘vertical-right’ value of ‘text-orientation’ to
    ‘upright-right’.
  - Renamed ‘rotate’ values of ‘text-orientation’ to ‘sideways’.
  - Renamed ‘auto’ value of ‘text-orientation’ to
    ‘use-glyph-orientation’ and marked it at-risk.
  - Tweaked rules for vertical typesetting to remove references to vrt2
    feature, fix various errors and omissions in synthesis rules, etc.
  - Renamed ‘text-combine’ property to ‘text-combine-horizontal’ and
    added ability to auto-combine by character classes.
  - Added ‘text-combine-mode’ property to control scaling method used to
    compose horizontal-in-vertical text.
  - Added appendix on Characters and Properties.

As always, this mailing list, <www-style@w3.org>, is the preferred place 
for comments. If you send e-mail, please start the subject line with

    [css3-writing-modes]

as I did on this message. Some issues that we know about are already 
noted in the draft itself (marked with "Issue" and in red). Feedback on 
those is especially welcome.



For the CSS WG,
Bert
