How can I specify the content type of a response?

I'm trying to build some endpoints that return XML instead of JSON and I can't find a way to specify this in the responses. The documentation says that I need to provide a BaseModel, but I don't know of a way to attach a content type to it.

Additionally, I do not want to have to specify a full schema for the returned XML, since it is absolutely ginormous and because it's basically only a "data export" endpoint, it would be fine to type it as some string with Content-Type application/xml.

Okay, I figured it out. I can simply put the response schema in extra_responses like this:

extra_responses={
    "200": { "content": {
        "application/xml": { "schema": { "type": "string" }}
    }}
}
