XML Query and XPath Data Model Updated

The XML Query and XSL Working Groups have released an updated Candidate Recommendation of XQuery 1.0 and XPath 2.0 Data Model (XDM). Both XSLT 2 and XQuery use XPath expressions and operate on XDM instances such as documents and databases. The group also released an updated Working Draft of the XQuery Update Facility which provides expressions to create, modify and delete nodes. Visit the XML home page. (Archivio News inglese, italiano)
