Additional context

As asked here it would be great to have the same validation currently available for Bread also for Settings, this is because you might have users that have to set a number as a settings but turn on adding invalid characters upon setting their settings.

For example we choose a textarea where a customer should typ only numbers, but instead the customer (user) is using text and therefore the input is invalid but did get accepted by the system.

It would be awesome to be able to set de validation variables also for the settings page.
