Example: the XSL Transformations language specifies the behaviour of an XSLT processor. The specification describes an XML-based style sheet language that directs the operations of a processor, but it clearly states that conformance determinations apply to the processor, not the style sheets. Example: XML Query specifies the behaviour of a processor that takes the query language and fetches data, typically arranging that data in a convenient form for XML/Web use. It allows flexibility of the storage system from which data is fetched."@en .
