+// Path
+//   Used together with Path Templating, where the parameter value is actually part of the operation's URL.
+//   This does not include the host or base path of the API. For example, in /items/{itemId}, the path parameter is itemId.
+// Query
+//   Parameters that are appended to the URL. For example, in /items?id=###, the query parameter is id.
+// Header
+//   Custom headers that are expected as part of the request.
+// Body
+//   The payload that's appended to the HTTP request. Since there can only be one payload, there can only be one body parameter.
+//   The name of the body parameter has no effect on the parameter itself and is used for documentation purposes only.
+//   Since Form parameters are also in the payload, body and form parameters cannot exist together for the same operation.
+// Form
+//   Used to describe the payload of an HTTP request when either application/x-www-form-urlencoded, multipart/form-data
+//   or both are used as the content type of the request (in Swagger's definition, the consumes property of an operation).
+//   This is the only parameter type that can be used to send files, thus supporting the file type. Since form parameters
+//   are sent in the payload, they cannot be declared together with a body parameter for the same operation. Form
+//   parameters have a different format based on the content-type used (for further details,
+//   consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4):
+//     application/x-www-form-urlencoded - Similar to the format of Query parameters but as a payload. For example,
+//     foo=1&bar=swagger - both foo and bar are form parameters. This is normally used for simple parameters that are
+//                         being transferred.
+//     multipart/form-data - each parameter takes a section in the payload with an internal header. For example, for
+//                           the header Content-Disposition: form-data; name="submit-name" the name of the parameter is
