W3C published two Recommendations today: XQuery Update Facility 1.0 and XQuery and XPath Full Text 1.0. The former defines an update facility that extends the XML Query language, XQuery. The XQuery Update Facility provides expressions that can be used to make persistent changes to instances of the XQuery 1.0 and XPath 2.0 Data Model. The latter extends XQuery 1.0 and XPath 2.0 with full-text search capabilities. The former document was published by the XML Query Working Group, the latter jointly with the XSL Working Group.

The Web Applications Working Group has published a Last Call Working Draft of HTML5 Web Messaging. Web browsers, for security and privacy reasons, prevent documents in different domains from affecting each other; that is, cross-site scripting is disallowed. While this is an important security feature, it prevents pages from different domains from communicating even when those pages are not hostile. This specification defines two mechanisms for communicating between browsing contexts in HTML documents. Comments are welcome through 01 June. Learn more about the Rich Web Client Activity.

The Media Fragments Working Group has published a Last Call Working Draft of Media Fragments URI 1.0. Audio and video resources on the World Wide Web are currently treated as "foreign" objects, which can only be embedded using a plugin that is capable of decoding and interacting with the media resource. Specific media servers are generally required to provide for server-side features such as direct access to time offsets into a video without the need to retrieve the entire resource. Support for such media fragment access varies between different media formats and inhibits standard means of dealing with such content on the Web. This specification provides for a media-format independent, standard means of addressing media fragments on the Web using URIs. Comments are welcome through 10 April. Learn more about the Video in the Web Activity.

The Device APIs and Policy Working Group has published a Group Note of Device API Access Control Use Cases and Requirements.
