6 Package SOAP APIs for C++

W3C: "SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelope that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing remote procedure calls and responses."

The structure of a SOAP message is:

[SOAP message (XML document)
   [SOAP envelope
      [SOAP header?
      [SOAP body
           (element* | Fault)?
