Multiple custom elements

Hello everyone,

I currently have a single custom element, based on the custom-elements example, where I am extending the bpmn:DataStoreReference with some custom attributes. This is all working well.

However, now I want to extend the DataStoreReference with some other custom properties, but not at the same time. Is this possible in any way? Ideally I would have a custom:DataStoreReferenceA and a custom:DataStoreReferenceB. But as far as I know, it is not possible with moddle, to create new top-level elements. That are BPMN compliant at least.

But could I extend the panel and like in the example but instead of the same element with different values for the properties, the same element with different custom properties?

Thanks in advance
