The Timed Text Working Group has published a Last Call Working Draft of Simple Delivery Profile for Closed Captions (US). This document, expected to become a Group Note, specifies the Simple Online Delivery Profile (US) of the Timed Text Markup Language (TTML). The primary goal of the profile is to establish a minimum level of interoperability between TTML10 and legacy caption formats employed in US markets, such as CEA608 and CEA708. Comments are welcome through 31 January. Learn more about the Video in the Web Activity.

The Cascading Style Sheets (CSS) Working Group published a Last Call Working Draft of CSS Text Decoration Module Level 3. This module contains the features of CSS relating to text decoration, such as underlines, text shadows, and emphasis marks. Comments are welcome through 31 January.

The group also published today a draft of CSS Cascading and Inheritance Level 3. One of the fundamental design principles of CSS is cascading, which allows several style sheets to influence the presentation of a document. When different declarations try to set a value for the same element/property combination, the conflicts must somehow be resolved. The rules for finding the specified value for all properties on all elements in the document are described in this specification. Learn more about the Style Activity.
