 In order to modify the `req.params`, express requires that a param handler be registered e.g. `app.param(...)` or `router.param(...)`. Since `app` is available to middleware functions, the validator registers an `app.param` handler to coerce and modify the values of `req.params` to their declared types. Unfortunately, express does not provide a means to determine the current router from a middleware function, hence the validator is unable to register the same param handler on an express router. Ultimately, this means if your handler function is defined on `app`, the values of `req.params` will be coerced to their declared types. If your handler function is declare on an `express.Router`, the values of `req.params` values will be of type `string` (You must coerce them e.g. `parseInt(req.params.id)`).
