### Modelo para Entrada y Salida en la Documentación

Y si revisas todos los esquemas disponibles (JSON Schemas) en OpenAPI, verás que hay dos, uno `Item-Input` y uno `Item-Output`.

Para `Item-Input`, `description` **no es requerido**, no tiene un asterisco rojo.

Pero para `Item-Output`, `description` **es requerido**, tiene un asterisco rojo.
