There are two types of validation rules: task-level and directory-level.
If a managed object attribute is associated with a validation rule,
applies the rule when the attribute value is set.
enforces validation rules when a business logic task handler calls a setAttribute... method in AttributeCollection to set an attribute. However,
only enforces directory-level validation for attributes set in this way. The reason is that when setAttribute... is called, the attribute value has already been set in the task screen field, and is currently being set in a managed object in the task session.
