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.

ISO DSDL Overview (2049 words)
Standing for "Document Schema Definition Languages", DSDL is a recognition that the validation of XML documents is a subject too wide and complex to be covered by a single language.
DSDL can be seen as a framework and set of languages to check the quality of XML documents and this issue appears to be crucial for any XML based application.
DSDL Part 9 is for these people who would like to rely on years of usage of DTDs without loosing all of the goodies of newer schema languages.
