C2WSDL12 — CORBA to WSDL/SOAP: example for attributes mapping

Section 1.2.8.2
In the example for attributes mapping.
The get accessor maps to an operation with only an output message. It seems like a notification operation according to WSDL specification. But the semantics of attribute accessors should be request-response .So a get accessor should be mapped to a couple of messages.
Proposed solution :
Define the incoming message as a message without any parameter as the following:
<message name="MyAttrs._get_strAttr" />
<message name="MyAttrs._get_strAttrResponse" >
<part name="_return" type="xsd:string"/>
</message>
¡­
<portType name="MyAttrs" >
<operation name="_get_strAttr" >
<output message="tns:MyAttrs._get_strAttrResponse"/>
<fault message=¡±tns:CORBA.SystemException¡±/>
</operation>
