Whether goJs supports rendering flowcharts directly based on BPMN's data format

The demo in goJs renders the flow chart in json format required by goJs, Can render flowchart directly in BPMN format?Thank you for answering my questions

The feature of reading and writing that particular XML schema has not been implemented by us. I suspect some of our customers have done that, but I’m not sure about that and we would not have access to that code in any case.

Thank you. Thank you very much
