Re: [netmod] New proposal: Yang Schema annotation

Hi Balazs,

I agree that such a mechanism would be pretty useful.

I think though that the deviation-based approach can be used without
further ado. Why do you think that the "deviate" statement cannot handle
extension statements? AFAICT, the following module satisfies all rules
of RFC 7950, and it is then up to an implementation to handle the
extension, so it can also add it as an annotation to the target node.

module devext {
  namespace "http://example.com/devext";
  prefix de;
  import ietf-interfaces {
    prefix if;
  }
  extension foo;
  deviation "/if:interfaces" {
    deviate "add" {
      de:foo;
    }
  }
}

Lada
