Web Services Description Language (WSDL) defines two styles for how an XML Web service method, or operation, can be formatted in a SOAP message: RPC and Document. RPC formatting refers to formatting the operation according to the SOAP specification for using SOAP for RPC; otherwise known as Section 7 of the SOAP specification. RPC formatting states that all parameters are encapsulated within a single XML element named after the XML Web service method and that each XML element within that XML element represents a parameter named after the parameter it is representing.
SOAP messages formatted in both the RPC and Document styles can be used to communicate with an XML Web service in a Remote Procedure Call (RPC) manner; however the Document style can also easily be used to communicate in a loosely coupled manner. Therefore, Document style XML Web services is recommended. For more details, see the Customizing SOAP Messages topic.

This attribute can be applied to an XML Web service method on the server and a proxy class on the client. XML Web service methods that have the SoapRpcMethodAttribute.OneWay property set to true do not have access to their System.Web.HttpContext. As such, accessing any of the properties of the System.Web.Services.WebService class return null.
