-You can validate translated STIX results from the CLI provided they conform to the 2.1 standard. The `--stix-validator` flag at the end will run validation on the returned STIX objects to ensure they conform to the STIX 2.1 standard. Alternatively, `'{ "stix_validator": true }'` can be passed in at the end as an options dictionary.
