XQuery, XSLT 2.0, and XPath 2.0 were approved by two working groups of the World Wide Web Consortium (W3C) in order to encourage efforts by enterprises to link databases onto the Web and direct the convergence of databases with document systems. While these three were the primary standards, five others were also adopted at the same time to offer new methods for accessing, converting, and querying XML documents and data. According to Michael Sperberg-McQueen, a contributor to the original XML 1.0 specification, the specifications give a necessary bridge between documents that have complicated and irregular internal structure and databases and simple data that have atomic values. XQuery is designed to provide a unified interface to access data from multiple sources. It makes it easier to query both structured and unconstrained schema. Early adopters of XQuery include relational database vendors, open-source projects, and middleware and XML-native database system vendors. XSLT 2.0 extends XSL transformation abilities further than the original specifications via a bigger library of functions, which maintain most backward compatibility. Additionally, it includes new grouping and aggregation options. XPath 2.0 is described as a superset of the original language. XPath is viewed as the standard method for locating objects in XML.
