Last Call: XQuery, XPath and XSLT

  The XML Query Working Group and the XSL Working Group released twelve
  Working Drafts for the XQuery, XPath and XSLT languages. Seven are in
  last call through 13 May. Important for databases, search engines and
  object repositories, XML Query can perform searches, queries and joins
  over collections of documents. XSLT transforms documents into different
  markup or formats. Both XQuery and XSLT 2 use XPath expressions and
  operate on XPath Data Model instances.

Working Draft: SVG's XML Binding Language (sXBL)

  The Scalable Vector Graphics (SVG) Working Group and the CSS Working
  Group have released a third Working Draft of "SVG's XML Binding
  Language (sXBL)." The sXBL language defines the presentation and
  interactive behavior of elements outside the SVG namespace. The XBL
  task force welcomes comments and seeks feedback on three issues
  outlined in the status section. Visit the SVG and CSS home pages.

Working Draft: Compound Document Use Cases and Requirements

  The Compound Document Formats Working Group has released an updated
  Working Draft of "Compound Document by Reference Use Cases and
  Requirements Version 1.0." A compound document combines multiple
  formats, such as XHTML, SVG, XForms, MathML and SMIL. This draft
  introduces compounding by a reference like img, object, link, src and
  XLink. Compounding by inclusion is planned for a later phase. Visit the
  Compound Document home page.
