This attribute is used to specify the encoding for SOAP request and response messages. You can apply this attribute to methods in a web service or in methods in a proxy class that derives from SoapHttpClientProtocol (where it's required to bind the messages to the appropriate web method). You use this attribute, instead of SoapDocumentMethodAttribute, when you want to use the RPC encoding standard.
There are two options for encoding XML information in a SOAP message: RPC and Document. ASP.NET's default is Document. RPC (found in section 7 of the SOAP specification) specifies that all method parameters be wrapped in a single element named after the web service method and that each element be named after their respective parameter name. If you apply this attribute to a web method, it will not be able to return objects because no XSD schema will be generated.
