Extensible Stylesheet Language (web) (XSL) A standard developed by the World Wide Web Consortium defining a language for transforming and formatting XML documents.
An XSL stylesheet is written in XML and consists of instructions for tree transformation and formatting. The tree transformations describe how each XML tag relates to other data and the formatting instructions describe how to output the various types of data. http://w3.org/Style/XSL/.
