Data::TreeValidator::Constraints - A collection of constraints for validating data
use Data::TreeValidator::Constraints qw( required );
Constraints currently take a single form, a subroutine reference. If the data does not validate, an exception will be raised (which is caught by process methods). If an exception is not raised, the data will be assumed to be valid.

Checks that a given input is between
$max. You do not have to specify both parameters, either or is also fine.
