Good day! Very late, but i checked with my company and it's free to use. I don't know if that qualyfies as "public domain" or "new-bsd" but i think so.
I just want to mention something i came across the last weeks: http://framework.zend.com/manual/en/zend.filter.input.html The Zend_Filter_Input It features many functions as my above example like - filtering - validating . Important for me is the attribute "allowEmpty" that allows fields to be empty, even with validators. I don't know if the Zend_Filter_Input class can be used for Zend_Form_Element_* but maybe its woth a look.
