You appear to be suffering from tunnel vision that all valadation is based on data type. Validation based on data type is fine, and when I want that I'll likely have an object that encapsulates more than just validation and so my classes that use that type won't need to do validation so providing a hook for the containing object isn't particularly attractive to me.

The point of validation in an object's "set" method is to validate the request against the state of the object and even cause the setting to impact the state of the object outside of just that particular member variable.
