WSDL Binding for SOAP 1.2.

Overview

There are three key differences from the SOAP 1.1 binding:

· A new namespace: http://schemas.xmlsoap.org/wsdl/soap12/

· The encodingStyle attribute is now a single URI, instead of a list of URIs

· There is a new attribute: soapActionRequired, which is used to indicated that the server needs the SOAPAction value.

Example
