The name attribute provides a unique name among all ports defined within the enclosing WSDL document. WSDL supports the XML Schemas specification (XSD) as its type system. When you save a newly-created «WSDLbinding» stereotyped Class, the system: Adds to the Binding diagram, the WSDL Port Type element implemented by the WSDL Binding. This is an important aspect of the client application, because if the web service works with a complex data type, then the client application should know how to process the complex data type.

Binding extensibility elements are used to specify the address information for the port. The Wsutil.exe utility generates a C language stub according to supplied WSDL metadata, as well as data type definitions and descriptions for data types described by user-authored XML schemas.. A port cannot specify more than one address. For example, if the port name is "ExampleSoap," the value for this parameter would be ExampleSoap. A ServiceDescription instance contains a collection of ServiceEndpoint instances that each map to individual wsdl:portelements. The name attribute (you can use any name you want) defines the name of the binding, and the type attribute points to the port for the binding, in this case the "glossaryTerms" port.

What he did was just remove the two blocks of SOAP12 binding and this single line of code: The soap:binding element has two attributes - style and transport. service_name – The service name for the service binding. The element combines multiple message elements to form a complete oneway or round-trip operation. These element types build on one another with cascading references; so when you create a WSDL file, you should create the message section first, followed by the port type section, then the binding section, and finally the service section.
