Construct a complete SOAP message from the given literal elements children (the element
itself is a "dummy header") according to the instructions in the WSDL binding operation
defined in the operation given to either the input, output or fault element.
The IBPELDeployer interface represents a BPEL Deployer, i.e. an entity which is responsible for
deploying a given BPEL process into an engine, and also for undeploying it.
The IHeaderProcessor interface represents a SOAP Header Processor and is intended to be
implemented by concrete processors which, in turn, implement header protocols like WSA Adressing.
The ISOAPEncoder interface represents a SOAP Encoder, and is intended to be implemented by
providers of concrete style and encoding targets, like, for example, "document/literal".
The send package exists solely for communication with the header processor, allowing it to
retrieve the sending SOAP message for extensions and changing the target URL of this send
activity if appropriate.
