JSON Schemaの追加情報を宣言する方法はいくつかあります。

## Pydanticの`schema_extra`

<a href="https://docs.pydantic.dev/latest/concepts/json_schema/#schema-customization" class="external-link" target="_blank">Pydanticのドキュメント: スキーマのカスタマイズ</a>で説明されているように、`Config`と`schema_extra`を使ってPydanticモデルの例を宣言することができます:

```Python hl_lines="15 16 17 18 19 20 21 22 23"
{!../../../docs_src/schema_extra_example/tutorial001.py!}
```

その追加情報はそのまま出力され、JSON Schemaに追加されます。
