Type Mapping

The UML to XML Schema mapping rules are as follows:

Each UML class not derived from a built-in simple type (e.g. String) corresponds to an XML complex type.
Each UML attribute of simple type (or derived from a simple type) corresponds to an XML attribute of the XML complex type defined by the containing UML class.
Each UML attribute of a complex type is mapped to an XML element.

A consequence of this mapping is, that if a simple type can be switched from XML attribute to XML element representation by changing its UML presentation - being an UML attribute or association.
