Wildcard properties in Swagger?

I have a JSON response which may have any number of nodes, and the names may vary too. For example:

  thing: "this a thing"
  other: "this is another thing"
  another: "and yet another thing"

Is there a way to indicate it in Swagger that the object may contain any number of properties, each with any name?

type: object
    type: string
    repeats: infinitely
