XSLT 2.0, XML Query and XPath 2.0 Candidate Recommendations

The XML Query and XSL Working Groups have released updated Candidate Recommendations of XML Query 1.0, XSLT 2.0, XPath 2.0 and supporting documents. The XQuery use cases are also updated. Today's drafts incorporate comments received at Candidate Recommendation and move the xdt:* types to the XML Schema xs namespace, a change made in conjunction with the XML Schema Working Group. XSLT transforms documents into different markup or formats. Important for databases, search engines and object repositories, XML Query can perform searches, queries and joins over collections of documents. Both XSLT 2 and XQuery use XPath expressions and operate on XPath Data Model instances. Visit the XML home page.
