我希望有一个描述值的模式，例如JSON模式本身

{
  "title": "Schema modification event",
  "description": "Describes and event of modification of another (arbitrary) JSON schema",
  "type": "object",
  "properties": {
    "field_name": {
      "type": "string",
      "format": "json-pointer",
      "description": "Location where change occurred"
    },
    "field_schema": {
      "$ref": "https://json-schema.org/draft-07/schema",
      "description": "New schema of the location"
    }
  },
  "required": [
    "field_name",
    "field_schema"
  ]
}
