This repository holds a demonstration of the problem described in Issue #2975 (The mutually-exclusive url and identifier properties of License object are optional in specification and required in schema) and proposes various solutions.
Everything is done with a test suite looping on all *schema.yaml file in schemas, the first one being the original schema of the OpenAPI Specification.
It checks that all documents in samples/valid and sampled/invalid are respectively valid and invalid according to the selected schema.
The code is an adaptation of the test.js script of the OpenAPI Specification github repository.
