* 適当な型に変換します（必要な場合）。
* データを検証します。
    * データが無効な場合は、明確なエラーが返され、どこが不正なデータであったかを示します。
* 受け取ったデータをパラメータ `item` に変換します。
    * 関数内で `Item` 型であると宣言したので、すべての属性とその型に対するエディタサポート（補完など）をすべて使用できます。
* モデルの<a href="http://json-schema.org" class="external-link" target="_blank">JSONスキーマ</a>定義を生成し、好きな場所で使用することができます。
* これらのスキーマは、生成されたOpenAPIスキーマの一部となり、自動ドキュメントの<abbr title = "User Interfaces">UI</abbr>に使用されます。
