                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

                app = FastAPI()

                app.openapi_version = "3.0.2"
