This document type is described in pub.prt.CallActivityModel. When invoking a process with dynamic process behavior, it is possible to populate the pub.prt.CallActivityModel document list to invoke two or more callable processes.

Multiple entries in the pub.prt.CallActivityModel list with the same CallActivityModelId value are supported. The output document list with the name specified in the OutputPipelineName field contains all entries from executed models where the WaitForCallActivity parameter is set to true. The order of the documents in the output document list is the same as the order in the pub.prt.CallActivityModel input list.
