/// Overrides IsAttributeUsed(Object). The default implementation recursively calls IsAttributeUsed for all children (if any) and then checks the usage for all attributes implemented by CADability. No checks are performed for non CADability attributes. So you can override this method to handle your own attributes and call the base implementation for CADability attributes.
