  * `path`: the path where this definition was found, to enable us to resolve "$ref"
  * `anchor_base`: a prefix to add to the HTML anchors generated for each object

  This template renders:
  * the "simple parameters" (header, path, query parameters)
  * body parameters, which may be more complex, containing nested objects
  * response body examples
