{
  "type": "Query",
  "properties": {
    "dodiCode": "designs_exampleJobs",
    "attributes": ["all"]
  },
  "children": [
    {
      "type": "Equals",
      "children": [
        {
          "type": "Subtract",
          "children": [
            {
              "type": "Attribute",
              "properties": {
                "attributeCode": "attributes_jobsConeCount"
              }
            },
            {
              "type": "Attribute",
              "properties": {
                "attributeCode": "attributes_jobsSafetyLightsCount"
              }
            }
          ]
        },
        {
          "type": "Number",
          "value": ["5"]
        }
      ]
    }
