An '''XML Schema Definition''' (XSD) is a file defining a particular set of data types and structural rules for a class of [[XML]] documents, which is itself expressed in XML form. The standard for it was adopted by the W3C (World Wide Web Consortium) in May, 2001. It was intended as a more flexible and extensible method of defining XML file format characteristics than the older method of using [[DTD]]s (Data Type Definitions), since a document can have only one DTD, but can have multiple XSDs to define namespaces used in the document.

[[DFDL]] (Data Format Definition Language) is a variety of XSD with additional annotations to specify particular (binary or text) data file formats in a file which can be of a non-XML variety, allowing arbitrary file formats to be mapped onto particular XML file formats encompassing their content and structure.
