Si te comunicas con esa *path operation* enviando dos headers HTTP como:

```
X-Token: foo
X-Token: bar
```

El response sería como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulación

Declara headers con `Header`, usando el mismo patrón común que `Query`, `Path` y `Cookie`.
