そのため、OpenAPIでは同じ目的のために<a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#fixed-fields-20" class="external-link" target="_blank">`example`</a>を独自に定義しており（`examples`ではなく`example`として）、それがdocs UI（Swagger UIを使用）で使用されています。

つまり、`example`はJSON Schemaの一部ではありませんが、OpenAPIの一部であり、それがdocs UIで使用されることになります。
