Specific mapper subflow

The specific body mapper subflows are straightforward. They start with a label node that acts as the target for the RouteToNextMapper subflow. This is followed by a compute node that maps the ISF XML body into the MTXML block 4 subtree. Finally, it calls the RouteToNextMapper subflow, which sequences the next label in the routing list and ultimately back to the ISFToFIMMapper subflow once all of the body mapper subflows are complete. The following figure shows an example of a body mapper subflow.
