{{Refimprove|date=March 2009}}
'''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 as a multi-part [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]] Standard, ISO/IEC 19757.<ref>{{cite web |url=http://kikaku.itscj.ipsj.or.jp/sc34/ |title=Iso/Iec JTC 1/Sc 34 |accessdate=2009-12-25 |url-status=dead |archiveurl=https://web.archive.org/web/20140506050220/http://kikaku.itscj.ipsj.or.jp/sc34/ |archivedate=2014-05-06 }}</ref> It was developed by [[ISO/IEC JTC 1/SC 34]] (ISO/IEC Joint Technical Committee 1, Subcommittee 34 - Document description and processing languages).<ref>{{cite web | url=http://www.iso.org/iso/iso_technical_committee.html?commid=45374 | title=JTC 1/SC 34 - Document description and processing languages | author=ISO | date=5 March 2008 | publisher=ISO | accessdate=2009-12-25}}</ref><ref>{{cite web |url=http://kikaku.itscj.ipsj.or.jp/sc34/ |title=JTC 1/SC 34 - Document Description and Processing Languages |author=ISO JTC1/SC34 |accessdate=2009-12-25 |url-status=dead |archiveurl=https://web.archive.org/web/20140506050220/http://kikaku.itscj.ipsj.or.jp/sc34/ |archivedate=2014-05-06 }}</ref>

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

* Part 2: Regular-grammar-based validation – [[RELAX NG]]
* Part 3: Rule-based validation – [[Schematron]]
* Part 4: [[Namespace-based Validation Dispatching Language]] (NVDL)
* Part 5: Extensible Datatypes 
* Part 7: Character Repertoire Description Language (CREPDL)
* Part 8: Document Semantics Renaming Language (DSRL)
* Part 9: Namespace and datatype declaration in Document Type Definitions (DTDs) (Datatype- and namespace-aware DTDs)
