XML Schema
XML 1.0 supports DTDs that can define document structures.
XML Schema provides better support for applications, document structure, attributes, and data types.
Future versions of XML depend on XML Schema to define the type of XML documents.
- The structure (XML Schema Structure) of XML Schema defines the definition language of XML Schema.
- The data types of XML Schema define extensible data types for XML.
