The association between operation names and their request and response definitions is created by the PortType element in the WSDL, for example:

<portType name="AWSECommerceServicePortType"> ... <operation name="ItemSearch"> <input message="tns:ItemSearchRequestMsg" /> <output message="tns:ItemSearchResponseMsg" /> </operation>

In this example, the operation, ItemSearch, is associated with its request and response definitions, ItemSearchRequestMsg and ItemSearchResponseMsg. The keywords, input and output, identify the operation's request and response definitions, respectively.
