This is the modification of example given in WfMC document WfMC TC-1016-X -"Interface 1: Process Definition Interchange Q&A and Examples".   The example is modified to show the most of JaWE possibilities (using ofentities from referenced external packages, putting set of activities into blockactivity, using extended attributes, defining data types and using it to definesome workflow relevant data, defining formal parameters of processes and passingactual parameters from SubFlow activities that reference these processes ...).   To see all of this, you have to open the document Business_Example.xpdl. Thepackage contained within this document contains 3 processes. Activities fromthese processes use participants from externally referenced package containedwithin Participant_Repository.xpdl, applications from externally referencedpackage contained within Application_Repository.xpdl and processes fromexternally referenced package contained within Process_Repository.xpdl.   The main process from this package is Sales Order Processing, and SubFlowactivities from this process references other processes from this package andfrom package defined within Process_Repository.xpdl   It is interesting to notice that you can remove external packagesParticipant_Repository and Application_Repository, because packageProcess_Repository also references these packages, so the main packagegets the references to these packages (which applications and participants mainpackage uses) through the Process_Repository package.
