XSL 1.0 was released as the W3C Recommendation 15. October 2001 as a language for expressing style sheets. It consists of the three parts: XSLT, XPath, and XSL Formatting Objects. An XSL style sheet specifies the presentation of a class of the XML documents by describing how an instance of the class is transformed into an XML document that uses the formatting vocabulary.

XSLT 1.0 was released as the W3C Recommendation 16. November 1999. XSLT is a language for transforming the XML documents into other XML documents.

XSLT 2.0 became W3C Working Draft 20. December 2002

XSL Formatting Objects is an XML vocabulary for specifying the formatting semantics. Formatting is the process of turning the result of the XSL transformation into a suitable output form for a reader or listener. No separate W3C document exists for the XSL Formatting Objects, but a description can be found inside the XSL 1.0 Recommendation.
