The semantics of pasting into a sequence diagram are ambiguous and limited. The tools validates that any sequence diagram represent a valid control flow. The implementation of SequenceDiagramRenderer requires at most one root call node. For this reason, the only pasting that really makes sense is of implicit parameter nodes. To make the behavior clearer, pasting into a sequence diagram will be disabled starting with 3.5
