UMLTP23 — CompoundProceduralElements

Given the constraints applied to the <<Alternative>> construct why would we not just simply have it extend the ConditionalNode instead of StructuredActivityNode?

See section 8.5.2.3.1

Same for <<Loop>> should be restricted to loop node metaclass

<<Parallel>> seems to have a contradiction between the description and the constraint "Application in Activities
In an Activity, «Parallel» must only be applied to SequenceNode". We think that this is meant to say a Conditional Node not a sequence node.
