### Modelo para Entrada y Salida en la Documentación { #model-for-input-and-output-in-docs }

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.
