YANG Versioning Weekly Call Minutes - 2021-04-13

Primary discussion was around the BC/NBC rules for state.

Value space for config false:
- more informative if you actually remove the enum from the model if it isn't used anymore (vs leaving it in and servers just not returning it)
- a server implementation should deviate if it doesn't return something ever (schema should try to accurately define the API)
- standard module -> remove the item if it isn't part of the API anymore
- NMDA operational DS has a copy of config true, so increased value space in config automatically casues increased value space in "state" (operational)
- a config true MTU in the operational DS and a dedicated config false "oper-mtu" leaf should have the same rules for increasing value space

Maybe a better formulation of the state rules is to take the 7950 rules and apply minimal text changes. Rob will take a stab at this.

7950:
   o  A "must" statement may be removed or its constraint relaxed.

Adjusted 7950 text:
   o  A "must" statement may be added, removed, or changed


7950:
   o  A "range", "length", or "pattern" statement may expand the allowed
      value space.
Adjusted 7950:
   o  A "range", "length", or "pattern" statement may expand or reduce the allowed
      value space.
