Implements non-null validation for mandatory attributes. This validation rule is applied by the framework to an Entity Object that has the mandatory flag set for any of its an attributes. The method isMandatory() identifies manditory attributes.

This validator is invoked by an Entity Objects's validate() method to confirm that its mandatory attributes are non-null. If any attribute is null, AttrValException is thrown. The framework does not perform this validation when an attribute value is changed, but only when its Enitity Object is validated.
