The XMLType class defines constants of type javax.xml.namespace.QName that represent various XML Schema and SOAP data types. The values defined by this class are used in the JAX-RPC API where it is necessary to refer to the XML representation of particular data types�for example, the addParameter( ) method of the javax.xml.rpc.Call interface, which uses these constants as the value of an argument that describes the XML data type of a method call to be made using the JAX-RPC dynamic invocation interface.
