it is BPMN 2 supported, then why sub-process many start events other than BPMN 2 standard which sho
does Bizagi fully comply with BPMN 2
i noticed that a sub-process can have start events other than "none start event" in Bizagi Modeler
it is not correct and not a BPMN 2 standard which should accept only "none start event"
please check OMG BPMN Page 241 last line to double check,
