The WAI Education and Outreach Working Group (EOWG) has published The Business Case for Digital Accessibility.

It describes how accessibility can drive innovation, enhance your brand, extend market reach, and minimize legal risk. It includes direct and indirect benefits of accessibility and the risks of not addressing accessibility adequately. It provides case studies and examples that demonstrate how investment in accessibility is good for your organization.

The Timed Text Working Group has published the following specifications as W3C Recommendations:

• Timed Text Markup Language 1 (TTML1) (Third Edition)
• Timed Text Markup Language 2 (TTML2)
• TTML Profiles for Internet Media Subtitles and Captions 1.1

The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. TTML Profiles are intended to be used across subtitle and caption delivery applications worldwide, thereby simplifying interoperability, consistent rendering and conversion to other subtitling and captioning formats.

The CSS Working Group invites implementations of two updated Candidate Recommendations:

• CSS Containment Module Level 1 describes the ‘contain’ property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.
• CSS Flexible Box Layout Module Level 1 describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc.

The Distributed Tracing Working Group has published a First Public Working Draft of Trace Context. A distributed application is an application that consists of multiple components, also known as micro-services, that are deployed and operated separately. The Trace Context specification defines properties intended for event correlation between micro-services to allow various tracing and diagnostics monitoring products to operate together.
