wsdl:DescriptionType

        Although correct, this type declaration does not capture
        all the constraints on the contents of the wsdl:description
        element as defined by the WSDL 2.0 specification.

        In particular, the ordering constraints wrt elements preceding
        and following the wsdl:types child element are not captured, as
        attempts to incorporate such restrictions in the schema
        ran afoul of the UPA (Unique Particle Attribution) rule
        in the XML Schema language.

        Please refer to the WSDL 2.0 specification for
	additional information on the contents of this type.
