This is what I meant by "TBD" above.  Undoubtedly, the notification-messages
draft will need to see if there is another way to achieve its end and, if
not, we (NETMOD) will be asked to define an "augment-yang-data" draft, which
just defines the "augment" part of this draft on top of RFC 8040 rc:yang-data.

To those who say that we need a new version of YANG to do this properly, it
seems that we're making an argument for starting YANG-next now.
