When used as a local definition, the definition is done by assigning a simple or complex datatype to the element. This assignment can be done either by reference, using the type attribute to refer to a simple or complex datatype by its qualified name, or inline, by embedding the definition of the simple (xs:simpleType) element or complex (xs:complexType ...
