Foundational UML

InterruptibleRegion – Interruptible regions are excluded from fUML because they are considered to be more appropriate for “higher level” process modeling and outside the scope of fUML.

fUML1.4: 7.11.2.6 ExpansionNode: [2] fuml_expansion_node_no_crossing_edges: Edges may not cross into or out of an expansion region.

fUML1.4: Cameo Simulation Toolkit: LIMITATION: CreateObjectAction is not allowed to instantiate a UML DataType or a SysMLValueType, only a Class as the CreateObjectAction::classifier! WORKAROUND: Use a ValueSpecificationAction instead with an instance.

fUML1.4: 7.11.2.5: CreateObjectAction [1] fuml_create_object_action_is_class: The given classifier must be a class. self.classifier.oclIsKindOf(Class)

UML: Cameo Simulation Toolkit 19SP3: GOTCHA: CreateObjectAction ignores an Artifact as 'classifier' even though Artifact is a Classifier

GOTCHA: UML/SysML: Cameo Simulation Toolkit 19SP3: A [true] or [false] guard on an ActivityEdge MUST be a LiteralBoolean, not just characters typed in, or the evaluation may give unexpected or ill-defined results

UML/SysML: Cameo Simulation Toolkit 19SP3: A parent Activity with a DecisionNode that uses a Activity as a decisionInput Behavior terminates immediately after the decisionInput terminates (but OpaqueBehavior works)

UML/SysML: Cameo Simulation Toolkit 19SP3: GOTCHA: Will not evaluate a guard using a token from a decisionInputFlow UNLESS a decisionInput Behaviour is explicitly defined (but Alf does)

ValuePin – Value pins are excluded from fUML because they are redundant with using value specifications to specify values.

Alf - the Action Language for Foundation UML - is a UML-friendly textual "surface language" intended for use together with fUML. Useful for those tasks in Activity and StateMachine diagrams that don't lend themselves to graphical modelling.
