Hi All,

RFC 8342 defines the conventional data-store as below

     identity conventional {
       base datastore;
         "Abstract base identity for conventional configuration

So when using the data-store-ref with NETCONF <get-data> as below:

<rpc message-id="101"

The libyang parser was successfully able to parse this as a valid data-store-ref. But conceptually this is not a valid data-store as it is an "abstract base identity".
NETCONF Server will have to add code to send error when conventional data-store comes in input.  I would prefer if we can control this using data-model statements then the parser can handle the error. Any thoughts ?

With Regards,
Rohit R Ranade
