UML24 — Resolution to issue 14063

Accepted resolution in UML 2.4 Ballot 8 for issue 14063 has a problem because ActivityGroup::inActivity needs to refer to StructuredActivities::Activity

The accepted resolution for 14063 in Ballot 8 states the following:
“In the UML 2.3 Superstructure Specification, Subclause 12.2 Abstract Syntax, in Figures 12.21 and 12.22, replace the unqualified ActivityGroup classes on the diagrams with the qualified UML::Activities::FundamentalActivities::ActivityGroup class. Remove the StructuredActivities::ActivityGroup and CompleteStructuredActivities::ActivityGroup classes from the metamodel.”
The problem is that ActivityGroup in StructuredActivities refers, via its property inActivity, to Activity in StructuredActivities. Removing StructuredActivities::ActivityGroup deprives this property of a home. Hence we need to reinstate the copies of ActivityGroup.
Then we also need to copy down Action into CompleteStructuredActivities, and its associations input and output, so that the structuredNodeInput

and structuredNodeOutput

work correctly, i.e. subset the correct types of InputPin and OutputPin.
Note than none of this will have any effect on the merged definition of UML.
