/**
 * Service provider interface for registering custom {@link Type} implementations.
 * <p>
 * This interface allows plugins and extensions to define and register additional artifact types
 * beyond the standard ones provided by Maven (like jar, war, pom, etc.). Types define how artifacts
 * are handled, including their default extension, classifier, and language.
 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism

Por ejemplo, vamos a añadir <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">la extensión OpenAPI de ReDoc para incluir un logo personalizado</a>.

### Extensions OpenAPI

Cet `openapi_extra` peut être utile, par exemple, pour déclarer [OpenAPI Extensions](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#specificationExtensions) :

{* ../../docs_src/path_operation_advanced_configuration/tutorial005.py hl[6] *}

Si vous ouvrez la documentation automatique de l'API, votre extension apparaîtra au bas du *chemin* spécifique.

Este es un punto de extensión de bajo nivel.

Si solo necesitas declarar responses adicionales, una forma más conveniente de hacerlo es con [Responses Adicionales en OpenAPI](additional-responses.md){.internal-link target=_blank}.

Puedes extender el esquema de OpenAPI para una *path operation* usando el parámetro `openapi_extra`.
