List Response Model

I want to document my response model as a list of strings like: 
```
[
    "value1", 
    "value2"
]

```
which is valid JSON.
So I want to be able to do something like: 
```
response_model = ns.model('Response', [
    fields.String()
])
```

Is there a way of doing this currently without having to use a dict object in ns.model?
