This type is extended by component types to allow them to be documented. This type is extended by component types to allow attributes from other namespaces to be added. This element serves as the head of a substitution group for extensibility elements that wish to appear as a child of any element in wsdl that has complex content This element serves as the head of a substitution group for extensibility elements that wish to appear as a child of wsdl:message and/or wsdl:portType This element serves as the head of a substitution group for extensibility elements that wish to appear as a child of wsdl:message, wsdl:portType and/or wsdl:binding This element serves as the head of a substitution group for extensibility elements that wish to appear as a child of wsdl:message, wsdl:portType, wsdl:binding and/or wsdl:service This element serves as the head of a substitution group for extensibility elements that wish to appear as a child of wsdl:binding and/or wsdl:service This element serves as the head of a substitution group for extensibility elements that wish to appear before the wsdl:import/wsdl:include elements This element serves as the head of a substitution group for extensibility elements that wish to appear interleaved with the wsdl:import/wsdl:include elements This element serves as the head of a substitution group for extensibility elements that wish to appear after the wsdl:import/wsdl:include elements but before the wsdl:types element This element serves as the head of a substitution group for extensibility elements that wish to appear after the wsdl:types element ( potentially interleaved with wsdl:message/portType/binding/service This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:message This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:message before wsdl:part This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:message after wsdl:part This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:message/wsdl:part This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType before wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType after wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType/wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType/wsdl:operation/wsdl:input\output This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:portType/wsdl:operation/wsdl:fault This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding before wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding after wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding/wsdl:operation This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding/wsdl:operation/wsdl:input/output This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:binding/wsdl:operation/wsdl:fault This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:service This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:service before wsdl:port This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:service after wsdl:port This element serves as the head of a substitution group for extensibility elements that wish to appear as children of wsdl:port Any top-level, optional element is allowed to appear more than once - Any extensibility element is allowed in any place. Such extensibility elements must be in the substitution group of globalExt or postTypes Either the element attribute OR the type attribute may appear but not both. Alternatively a qualified extensibility attribute which refers to constructs in some type system other than XML Schema may be used. This abstract type is intended to serve as the base type for extensibility elements. It includes the wsdl:required attribute which it is anticipated will be used by most extension elements
