// These tests require full documents to be tested properly. schemas are perhaps the most complex
// of all the things in OpenAPI, to ensure correctness, we must test the whole document structure.
//
// To test this correctly, we need a simulated document with inline schemas for recursive
// checking, as well as a couple of references, so we can avoid that disaster.
// in our model, components/definitions will be checked independently for changes
// and references will be checked only for value changes (points to a different reference)
