 *
 * Use this to e.g. check a JSON object received in an HTTP request. Example usage (for an express request handler):
 *
 * ```ts
 * const maybeBoardingPolicyType = validateBoardingPolicyType(req.body); // `req.body` will have type `any` or `unknown`
 * if (maybeBoardingPolicyType instanceof OaValidationError) {
 *   // From this point on, `maybeBoardingPolicyType` will have type `OaValidationError`
 *   const error = maybeBoardingPolicyType;
 *   // Do something with the error. Maybe ignore it? Or log it? Or throw? Up to you.
 * }
 * // From this point on, `maybeBoardingPolicyType` will have type `BoardingPolicyType`
 * const boardingPolicyType = maybeBoardingPolicyType;
