XML Schema

XML 1.0 supports DTDs that define the structure of the document.

XML Schema has better support for applications, document structures, attributes and data types.

Future versions of XML will rely on XML Schema to define the type of XML document.

• The structure of XML Schema (XML Schema Structure) specifies the definition language of XML Schema.

• XML Schema data types specify extensible data types for XML.
