The Cascading Style Sheets (CSS) Working Group published three drafts today:

• a First Public Working Draft of CSS Conditional Rules Module Level 3, which describes the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. This module contains the features of CSS for conditional processing of parts of style sheets, conditioned on capabilities of the processor or the document the style sheet is being applied to.
• a draft of CSS Text Level 3, which defines properties for text manipulation and specifies their processing model. It covers line breaking, justification and alignment, white space handling, text decoration and text transformation.
• a draft of CSS Writing Modes Module Level 3, which defines CSS features to support for 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).

W3C today published the final report of the W3C Identity in the Browser workshop, hosted by Mozilla 24-25 May in Mountain View, California. More than 80 representatives from various organizations participated, including major browser developers such as Google, Microsoft, Apple, Mozilla, and Netflix as well as companies wanting a more secure identity mechanism for the Web, such as Workshop sponsors RSA, Paypal, and Yahoo!. The report suggests opportunities for standardization to make the Web a more secure platform, in particular by enabling identity to be built on top of reliable cryptography in the browser. W3C is now developing a draft Working Group charter; contact Harry Halpin if interested.
