function ajax_forms_test_validation_form

This form and its related submit and callback functions demonstrate not validating another form element when a single Ajax element is triggered.

The "driver_text" element is an Ajax-enabled textfield, free-form. The "required_field" element is a textfield marked required.

The correct behavior is that the Ajax-enabled driver_text element should be able to trigger without causing validation of the "required_field".
