Disabling directive valdr-form-group dynamically using ng-attr - Does not work

Disabling directive valdr-form-group dynamically using ng-attr - Does not work properly. ng-attr was added in angular 1.3 on up. Can this module be enhanced to handle this or is it already in works?

{code}
 <div ng-attr-valdr-form-group="true|false">

  </div>
{code}
I was wondering if anyone else tried I will be  happy to look at this. This is nice feature.

Thanks
