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.
