20    The code to decapsulate and encapsulate parameters encoded in SOAP is the
21    same modulo a few parameters.  This is a functor that calls a fedd service
22    trhough a soap interface.  The parameters are the typecode of the request
23    parameters, the method to call (usually a bound instance of a method on a
24    fedd service providing class), the constructor of a response packet and
25    name of the body element of that packet.  The handler takes a ParsedSoap
26    object (the request) and returns an instance of the class created by
27    constructor containing the response.  Failures of the constructor or badly
28    created constructors will result in None being returned.
