Migration tool wrongly handles nodes inside super states and transitions between them

Nodes inside super states have qualified names which are used in transitions - for example "../super-state-A/node-X" targets to node-X inside super-state-A outside of actual super state. Two different super states both can have node of the same name. Migration tool however ignores super states and takes only their content without correcting the node names nor transitions. Output is an invalid bpmn2 definition with several elements having the same ID and sequenceFlow connecting non-existing elements.
