The Efficient XML Interchange Working Group has published a Proposed Edited 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. Comments are welcome through 20 November. Learn more about the Extensible Markup Language (XML) Activity.

The HTML Working Group has published three Working Drafts today:

• A First Public Working Draft of W3C HTML Ruby Markup Extensions. The ruby markup model currently described in the HTML specification is limited in its support for a number of features, notably jukugo and double-sided ruby, as well as inline ruby. This specification addresses these issues by introducing new elements and changing the ruby processing model. Specific care has been taken to ensure that authoring remains as simple as possible.
• A Working Draft of Polyglot Markup: A robust profile of the HTML5 vocabulary. A document that uses polyglot markup is a document that is a stream of bytes that parses into identical document trees (with some exceptions, as noted in the Introduction) when processed as HTML and when processed as XML. Polyglot markup that meets a well-defined set of constraints is interpreted as compatible, regardless of whether they are processed as HTML or as XHTML, per the HTML5 specification. Polyglot markup uses a specific DOCTYPE, namespace declarations, and a specific case—normally lower case but occasionally camel case—for element and attribute names. Polyglot markup uses lower case for certain attribute values. Further constraints include those on void elements, named entity references, and the use of scripts and style.
• A Working Draft of Encrypted Media Extensions. This proposal extends HTMLMediaElement providing APIs to control playback of protected content. The API supports use cases ranging from simple clear key decryption to high value video (given an appropriate user agent implementation). License/key exchange is controlled by the application. This specification does not define a content protection or Digital Rights Management system. Rather, it defines a common API that may be used to discover, select and interact with such systems as well as with simpler content encryption systems.
