[From W3C]
Based on widespread implementation experience and extensive feedback from users and vendors, W3C has published eight new standards in the XML Family to support the ability to query, transform, and access XML data and documents. The primary specifications are XQuery 1.0: An XML Query Language, XSL Transformations (XSLT) 2.0, and XML Path Language (XPath) 2.0; see the full list below.
These new Web Standards will play a significant role in enterprise computing by connecting databases with the Web. XQuery allows data mining of everything from memos and Web service messages to multi-terabyte relational databases. XSLT 2.0 adds significant new functionality to the already widely deployed XSLT 1.0, which enables the transformation and styled presentation of XML documents. Both specifications rely on XPath 2.0, also significantly enriched from its previous version.
