DFHWS-DATA is used to pass the request name and application data
to the stub program DFHMADPL when a Web service request is received and processed
in a provider mode pipeline.
The request name is 8 characters in length, and by default is the
same as the PROCESSTYPE resource for the service adapter. When this container
is passed by the pipeline application handler to the stub program, the default
values for the header are used in request processing. These default values
can be overridden by passing in additional containers.
The length of this
container can be up to, but not equal to, 16MB.
