    * リクエストとレスポンスでは`set`と同じように扱われます:
        * リクエストでは、リストが読み込まれ、重複を排除して`set`に変換されます。
        * レスポンスでは`set`が`list`に変換されます。
        * 生成されたスキーマは`set`の値が一意であることを指定します（JSON Schemaの`uniqueItems`を使用します）。
* `bytes`:
    * Pythonの標準的な`bytes`です。
    * リクエストとレスポンスでは`str`として扱われます。
    * 生成されたスキーマは`str`で`binary`の「フォーマット」持つことを指定します。
* `Decimal`:
    * Pythonの標準的な`Decimal`です。
    * リクエストやレスポンスでは`float`と同じように扱います。

The files and form fields will be uploaded as form data and you will receive the files and form fields.

And you can declare some of the files as `bytes` and some as `UploadFile`.
