// Parameter a unique parameter is defined by a combination of a [name](#parameterName) and [location](#parameterIn).
//
// There are five possible parameter types.
// * Path - Used together with [Path Templating](#pathTemplating), 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` or
//
// `multipart/form-data` are used as the content type of the request (in Swagger's definition,
// the [`consumes`](#operationConsumes) 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
// `submit-name`. This type of form parameters is more commonly used for file transfers.
