UML22 — Section: 12.3.10

Associated fig. 184 does not show generalizations from FundamentalActivities for ActivityGroup or from Dependencies for NamedElement. The association activity:Activity[0..1] is not diagrammed in fig. 184. The description for the association represents:Element[0..1] needs rewording. Does it mean "An element constraining the behaviors invoked by the nodes in the partition" (constraining used as a verb) or "The element constraining behaviors that are invoked by the nodes in the partition (constraining used as the noun "constraining behaviors")? Fig. 184 shows additional associations: ContainedEdge:ActivityEdge[1..1] and containedNode:ActivityNode[1..1]. These need to be added to text. Add OCL notation to constraints.
