[netmod] Action and RPC statements [was Re: augment YANG 1.0 with YANG 1.1 OK?]

[Robert Wilton <[e-mail]>]

Hi ,

Separating out the issue regarding which datastore action and RPC apply 
to, we propose the following NEW text to the datastores draft:

6.2 Invocation of Actions and RPC Operations

   This section updates section 7.15. of RFC 7950.

   In YANG data models, the "action" statement may appear under "config
   true" and "config false" schema nodes.  While instances of both
   schema nodes may appear in <operational>, instances of "config true"
   schema nodes may also appear in other datastores.

   An NMDA compliant server MUST execute all actions in the context of
   <operational>.  Likewise, an NMDA compliant server MUST invoke all RPC
   operations in the context of <operational>, unless the RPC is explicitly
   defined as affecting other datastores (e.g., <edit-config>).

OK?

Thanks,
Rob
