Model XSD
XML schemas are modeled using UML Class diagrams. The XML Schema page of the Toolbox provides built-in support for the UML profile for XSD. This enables an abstract UML Class model to be automatically generated as a W3C XML Schema (XSD) file.

Alternatively: XML Schemas can also be modeled using the UML Profile for XSD.

Notes
| • | The UML attributes of the Classes map directly to XML elements or attributes |
| • | Classes have no methods since there is no meaningful correspondence between Class methods and XSD constructs |
Modeling Restrictions:
The following XML Schema constructs cannot be modeled in Enterprise Architect:
| • | appinfo |
| • | field |
| • | key |
| • | keyref |
| • | notation |
