             comma-separated list of required permissions for a specified domain object. If the
             current user has any of those permissions, then the tag body will be evaluated. If they
             don't, it will be skipped. An example might

 This will be shown if the user has either of the permissions 
 represented by the values "1" or "2" on the given object.
