1. A method for implementing (Simple Object Access Protocol) SOAP-based Web services via a programming language in a computing system, comprising: in connection with code that implements at least one SOAP-based Web service, identifying at least one (Simple Object Access Protocol) SOAP message attribute supported by an attribute provider, wherein the (Simple Object Access Protocol) SOAP message attribute is a (Simple Object Access Protocol) SOAP handling mechanism; declaring the (Simple Object Access Protocol) SOAP handling mechanism corresponding to the at least one SOAP-based Web service via a construct of said programming language, when compiling said code, communication with the attribute provider is performed, wherein the attribute provider queries a compiler for information about the (Simple Object Access Protocol) SOAP handling mechanism; generating at least one of additional code and data from the information for use at run-time when at least one of sending and receiving a (Simple Object Access Protocol) SOAP message for said at least one SOAP-based Web service occurs.
