The Efficient XML Interchange Working Group has published a W3C Recommendation of Efficient XML Interchange (EXI) Format 1.0 (Second Edition). This document is the specification of the Efficient XML Interchange (EXI) format. EXI is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. The EXI format uses a hybrid approach drawn from the information and formal language theories, plus practical techniques verified by measurements, for entropy encoding XML information. Using a relatively simple algorithm, which is amenable to fast and compact implementation, and a small set of datatype representations, it reliably produces efficient encodings of XML event streams. The grammar production system and format definition of EXI are presented. Learn more about the Extensible Markup Language (XML) Activity.

The Math Working Group has published two Proposed Edited Recommendations today:

• Mathematical Markup Language (MathML) Version 3.0 2nd Edition. This specification defines the Mathematical Markup Language, or MathML. MathML is a markup language for describing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for text. Comments are welcome through 11 March.
• XML Entity Definitions for Characters (2nd Edition). This document defines several sets of names, so that to each name is assigned a Unicode character or sequence of characters. Each of these sets is expressed as a file of XML entity declarations. Comments are welcome through 11 March.

The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Shapes Module Level 1. CSS Shapes describe geometric shapes for use in CSS. For Level 1, CSS Shapes can be applied to floats. A circle shape on a float will cause inline content to wrap around the circle shape instead of the float’s bounding box. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Comments are welcome through 04 March. Learn more about the Style Activity.

The Device APIs Working Group has published a Last Call Working Draft of Vibration API. This specification defines an API that provides access to the vibration mechanism of the hosting device. Vibration is a form of tactile feedback. Comments are welcome through 04 March. Learn more about the Ubiquitous Web Applications Activity.

The SVG Working Group has published a Working Draft of Scalable Vector Graphics (SVG) 2. This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 2, a language for describing two-dimensional vector and mixed vector/raster graphics. Although an XML serialization is given, processing is defined in terms of a DOM. Learn more about the Graphics Activity.

The Web Application Security Working Group has published a Working Draft of Content Security Policy 1.1. This document defines a policy language used to declare a set of content restrictions for a web resource, and a mechanism for transmitting the policy from a server to a client where the policy is enforced. Learn more about the Security Activity.

The Web Performance Working Group has published a First Public Working Draft of Navigation Error Logging. This specification defines an interface to store and retrieve error data related to the previous navigations of a document. Learn more about the Rich Web Client Activity.
