Todo el proceso que aplicaba a los parámetros de path también aplica a los parámetros de query:

* Soporte del editor (obviamente)
* <abbr title="convertir el string que viene de un HTTP request a datos de Python">"Parsing"</abbr> de datos
* Validación de datos
* Documentación automática

## Configuraciones por defecto

Como los parámetros de query no están fijos en una parte del path pueden ser opcionales y pueden tener valores por defecto.
