XML Schema Quick Reference

XML Schema is a major W3C-standard which can be seen as a successor to the DTD which was developed in the first days of XML. You resort to XML Schema when you define your data model for XML messages and create elements and their hierarchical structure or attributes, keys and foreign keys.

XML Schema is a much richer language than DTD and contains even object-oriented concepts like inheritance for both so-called simple and complex data types.

This Quick Reference provides you with an overview of nearly all the language elements of XML Schema.
