Is there a way to check for particular parent path so that a container or leaf in a grouping would be present ONLY when it  is “used” from a particular path? For example:

grouping foo {
  container foo {
    container red {
         when “../../red-parent”;
    }
    container blue {
          when “../../blue-parent”;
     }
   }
}


container red-parent {
  uses foo;
}
 container blue-parent {
   uses foo;
}

It compiled fine using pyang but the check didn’t exclude the container with the non-matching parent from the path in the formatted tree (pyang -f tree output).

Thanks,
Acee
