A string será verificada para se tornar uma URL válida e documentada no esquema JSON/1OpenAPI como tal.

## Atributos como listas de submodelos

Você também pode usar modelos Pydantic como subtipos de `list`, `set`, etc:

```Python hl_lines="20"
{!../../../docs_src/body_nested_models/tutorial006.py!}
```

Isso vai esperar(converter, validar, documentar, etc) um corpo JSON tal qual:

```JSON hl_lines="11"
