-## Limitations

-In addition to the limitations mentioned above, there are some portions of JSONSchema that are not implemented
-in GPTScript yet, such as `oneOf`, `anyOf`, and `allOf`. These will likely be implemented in the future.
-There may be some other aspects of OpenAPI definitions that are not yet handled by GPTScript.
