Common attributes for multiple schema files

Developers

Can someone help me with a way to add a common attribute to multiple flow schemas?

I have different schema files for different task types which are responsible for attributes of those tasks. I want to add a common attribute to all the schemas, but if I do so I get following error

Adding attributes from frontend by:

const modeler = ModelerService.getModeler();
const modeling = modeler.get('modeling');
const attrInfo = {};
attrInfo[key] = value;
modeling.updateProperties(el, attrInfo);

Here, key is the attribute name and value is the attribute value.

Schema file:

{
  "name": "voice",
  "uri": "http://some-company/schema/bpmn/ivr",
  "$schema": "http://json-schema.org/draft-07/schema",
  "description": "Properties for the voice file",
  "prefix": "voice",
  "xml": {
    "tagAlias": "lowerCase"
  },
  "types": [
    {
      "name": "voiceFile",
      "extends": [
        "bpmn:Task"
      ],
      "properties": [
        {
          "name": "taskType",
          "description": "This variable tells what type of task it is",
          "isAttr": true,
          "type": "String"
        },
        {
          "name": "taskName",
          "description": "hold task's name",
          "isAttr": true,
          "type": "String"
        },
        {
          "name": "isDisabledVoice",
          "isAttr": false,
          "description": "tells if the element is disabled",
          "type": "String"
        }
      ]
    }
  ],
  "emumerations": [],
  "associations": []
}

You can have third model extension that adds attribute, otherwise you’d need to override the attribute of another extension which I don’t think is what you want.

@philippfromme I don’t want to override the attribute, because it raises conflicts. What exactly do I have to do for third model extension? Can you please elaborate. Thanks.
