SYSMLR — Item Flows on Activity Diagrams

Since ItemFlow is a stereotype of InformationFlow, it can be related to an ActivityEdge and depicted on an Activity Diagram. At least one tool has provided this capability. Clarify the use of ItemFlows on Activity Diagrams in the specification: If this is not desirable, then an additional constraint must be added to ItemFlows to prevent it. Personally, I like the idea of representing ItemFlows on ObjectFlows, but the semantic meaning of this representation is unclear. If this is retained, then it should be discussed in both chapter 9 and chapter 11.
