Extensible Stylesheet Language (XSL) associates presentation characteristics (e.g., layout) with the markup used in Extensible Markup Language (XML). One of the XML family of languages developed by the World Wide Web Consortium, XSL is used to create XML “stylesheets,” which describe how XML documents are presented. XSL provides independent control of presentation from content and can describe output of the same content to different formats (e.g., audio or print).

XSL is made up of three components: •     XSL Transformations (see XSLT) •     XML Path Language (see XPath) •     XSL Formatting Objects, an XML vocabulary for specifying formatting semantics
