	permission super_admin = administrator

	permission create_tenant = super_admin + administrator
}

      "comment": "represents a user of the system"
    },

              "type": "user"
            }
          ]
        }
      ],
      "permissions": [
        {
          "name": "super_admin",
          "userSet": {
            "operation": "union",
            "children": [
