* Enforcing RFC 7950 Sec 7.6.1 means unassigned top-level leafs (or leafs under non-presence containers) are assigned default values. * NACM default behaviour is read-only (empty configs are dead-lockedd) * This applies if NACM is loaded and `CLICON_NACM_MODE` is `internal` * Fixed: [default values don't show up in datastores #111](https://github.com/clicon/clixon/issues/111)
