The Efficient eXtended Interchange (EXI) Working Group has published a W3C Proposed Recommendation of Canonical EXI, a specification that describes the method for generating a canonical form of an EXI document. The main application of this specification is to guarantee non-repudiation using XML Signature, while allowing certain flexibility for intermediaries to reconstitute the documents before they reach final destination without breaking the signatures.

The Browser Testing and Tools Working Group has published a Proposed Recommendation of WebDriver. WebDriver is a remote control interface that enables introspection and control of user agents. It provides a platform- and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of web browsers. Provided is a set of interfaces to discover and manipulate DOM elements in web documents and to control the behavior of a user agent. It is primarily intended to allow web authors to write tests that automate a user agent from a separate controlling process, but may also be used in such a way as to allow in-browser scripts to control a — possibly separate — browser.

The Timed Text Working Group has published TTML Profiles for Internet Media Subtitles and Captions 1.0.1 (IMSC1) as a W3C Recommendation. This document specifies two profiles of [TTML1]: a text-only profile and an image-only profile. These 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. It is feasible to create documents that simultaneously conform to both [ttml10-sdp-us] and the text-only profile. The document defines extensions to [TTML1], as well as incorporates extensions specified in [ST2052-1] and [EBU-TT-D]. Both profiles are based on [SUBM].

The Accessibility Guidelines Working Group has published a Proposed Recommendation of Web Content Accessibility Guidelines (WCAG) 2.1. WCAG 2.1 covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content more accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These guidelines address accessibility of web content on desktops, laptops, tablets, and mobile devices. Following these guidelines will also often make Web content more usable to users in general.

The Timed Text Working Group invites implementations of Timed Text Markup Language 1 (TTML1) (Third Edition) Candidate Recommendation. This document specifies Timed Text Markup Language (TTML), Version 1, also known as TTML1, in terms of a vocabulary and semantics thereof. The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information. It is intended to be used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions. In addition to being used for interchange among legacy distribution content formats, TTML Content may be used directly as a distribution format, for example, providing a standard content format to reference from a <track> element in an HTML5 document, or a <text> or <textstream> media element in a [SMIL 2.1] document.
