How can I add a bpmndi:BPMNShape to a bpmndi:BPMNPlane in bpmn-moddle? Going by the diagram descriptors documenation bpmndi:BPMNPlane doesn’t have a property shape or something similar. Or should I add it in another way?
PS: I’ve asked this question in the comments of my previous question, but since it’s a separate question I’m posting it here as well.
