                avoid using features added in OpenAPI 3.1.0, it might work for your
                use case.

                This is not passed as a parameter to the `FastAPI` class to avoid
                giving the false idea that FastAPI would generate a different OpenAPI
                schema. It is only available as an attribute.

                **Example**

                ```python
                from fastapi import FastAPI
