title: Is it possible to specify an API response array (used as an ordered pair) in Swagger?
body: <p>I have a need to document an API via Swagger.
  The api response has 2 element arrays like this:</p>
  
  <p>[[RFC3339 timestamp, float64 value], ...]</p>
  
  <p>I am not sure how to define the ordered pair (which we use a 2 element array for). That is "[RFC3339 timestamp, float64 value]"</p>
  
  <p>Does anyone have any suggestions? 
  Thanks</p>
