Generally Ajax based validation is very limited as for example
it can't change foreign keys and so on. The "real" power
of cppcms form validation is in being able to overload
validate() function.

You can use some widgets data by for example calling

  <%= myform.my_widget.limits().first %>

to get minimal limit or some other stuff. Generally 
there is no direct support of client side validation as
it will always be limited.
