The message handlers are defined in an XML document,
which is stored in the HFS. The name of the file that contains the document
is specified in the CFGFILE attribute of a PIPELINE
definition.
The root element of the pipeline configuration document is the
<requester_pipeline> element.
The high-level structure of the document is shown in
Figure 1.
Figure 1. Structure of the pipeline
definition for a service requester.
Note: In order to simplify
the figure, child elements of the <handler>, <cics_soap_1.1_handler>,
and <cics_soap_1.2_handler> elements are not shown.

Some elements used in the pipeline configuration
for a service provider are also used in a service requester.
