Custom meta moddle

Hello guys,

I have a question regarding the custom meta moddle example. Is it possible to say that the suitable attribut is an array or is it only possible to say its integer, String etc

You can probably use the isMany attribute for it. As an example

  "name": "Process",
  "superClass": [
  "properties": [
      "name": "flowElements",
      "isMany": true,
      "replaces": "FlowElementsContainer#flowElements",
      "type": "FlowElement"
