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.
