Issue with when statement in openconfig-network-instance yang file

[bhramidi]

We are seeing an issue with the when statement with the latest network instance yang file.

https://github.com/openconfig/public/blob/e9e3a82693d1f26c61d7fbf85b3b2d0418d4af9e/release/models/network-instance/openconfig-network-instance.yang#L743

Line 743: the when statement should ideally be ‘when “./config/identifier = oc-pol-types:OSPF’ instead of just “./config/identifier =‘OSPF’ Same applies for all protocols (identifier types: BGP, ISIS, PIM etc.

We are seeing the following failure with when statement as it was expecting OSPF alone.

Even after changing the identifier to just "OSPF", we see the same issue. Could you please help us with this issue.

The qualification prefixes has been added and now is pending to be published.

 when "./config/identifier = 'oc-pol-types:OSPF'" {
                description
                  "Include OSPFv2 parameters only when the protocol
                  is of type OSPFv2";
              }
            }

@robshakir @aashaikh - it appears by the last comment this is likely resolved and also a pending PR https://github.com/openconfig/public/pull/482/files - when will this be published to public/master?
