Note: Protocol A might be used if user interface for PINT service requests
is (for example) a Web form. This would be submitted to a Web Server that
used an internal PINT Client to initiate a PINT Service request. It is not
required (for example, a program could "talk" PSP directly).

Protocol B is fairly similar; it MAY be used between an end User Interface
and an Application Layer Gateway that included both a SPIRITS Server and
an end node for this other program. It is not required; the SPIRITS Server
may execute the requested service directly (with any needed end User 
Interface).

Regards, Lawrence
