ElementConstraints:
Signature: same_name() : Boolean;
Description: Continuations with the same name may only cover the same set of Lifelines
(within one Classifier).
Expression: true
Signature: global() : Boolean;
Description: Continuations are always global in the enclosing InteractionFragment e.g.
it always covers all Lifelines covered by the enclosing InteractionFragment.
Expression: true
Signature: first_or_last_interaction_fragment() : Boolean;
Description: Continuations always occur as the very first InteractionFragment or the
very last InteractionFragment of the enclosing InteractionFragment.
Expression: true
