 - `lanelet2_validation_results.json` inherits the JSON file of `input_requirements` and add results to it.
-  - So non-required fields (line `version`) remains in the output.
+  - So additional input information not related to this validator also remains in the output.
 - `autoware_lanelet2_map_validator` adds a boolean `passed` field to each requirement. If all validators of the requirement have been passed, the `passed` field of the requirement will be `true` (`false` if not).
 - The `passed` field is also given to each validator. If the validator found any issues the `passed` field will turn to be `false` (`true` if not), and adds an `issues` field which is a list of issues found. Each issue contains information of `severity`, `primitive`, `id`, and `message`.
