The World Wide Web Consortium (W3C) has advanced the Extensible Stylesheet Language (XSL) 1.0 as a recommendation this week. XSL 1.0 is an XML-based language that details how XML documents will be formatted; it consists of two parts: "a language for transforming XML documents, and an XML vocabulary for specifying formatting semantics." XSL is the language that expresses stylesheets that enable XML documents or datasheets to be formatted into a Webpage, report, pamphlet, or other medium. XSL "introduces a model for pagination and layout that extends what is currently available."
