What would be the best way to document a binary response.

[tecbeast42]

I have a route where creates a pdf and returns the file binary with ->header('Content-Type', 'application/pdf'). I am not sure what would be the best way to document this.

I think something like this would be nice:

* @response <binary>

I think to just put it in the description is not a good way to solve this.

That could work. I'd prefer <<binary>> though, just to avoid the possibility of someone's response actually being "<binary>".
