Passing Parameters to a DPML program

DPML programs may use named parameters to accept argument values when invoked. For example, a DPML program may be run with the following URI:

active:dpml+operand@ffcpl:/myprog.idoc+data@ffcpl:/data.xml

Here the operand parameter is used by the DPML runtime to identify the program to be run and the data parameter is made available to the DPML program through the this:param: scheme. This DPML program will copy the contents of the resource made available through the parameter "data" to the response.
