| Description |
Developed under the auspices of the World Wide Web Consortium (W3C). "The purpose of the XML schema language is to provide an inventory of XML markup constructs with which to write schemas. The purpose of a schema is to define and describe a class of XML documents by using these constructs to constrain and document the meaning, usage and relationships of their constituent parts: datatypes, elements and their content, attributes and their values, entities and their contents and notations. Schema constructs may also provide for the specification of implicit information such as default values. Schemas document their own meaning, usage, and function." From XML Schema Requirements from W3C. |
