Document Schema Definition Languages (DSDL) is a framework within which multiple validation tasks of different types can be applied to an XML document in order to achieve more complete validation results than just the application of a single technology.

It is specified by the standard ISO/IEC 19757.

DSDL is a multipart standard defining a modular set of specifications for describing the document structures, data types, and data relationships in structured information resources.
