WSDL With Multiple Bindings

A service can be exposed on multiple protocols for e.g. web service having one operation exposed over SOAP/HTTP can also support SOAP/SMTP protocol. The only additional part required in WSDL is a binding element with correct transport. A sample WSDL is given below -

<wsdl:definitions name="ValidationService" targetNamespace="http://xmlns.oracle.com/NTApplication/ValidationService" xmlns:client="http://xmlns.oracle.com/NTApplication/ValidationService" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
