Cannot discover netconf device

While trying to get a netconf based device recognized by ODL, it was found that the initial RPC request was as below

<rpc message-id="m-25" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <get-schema xmlns="urn:ietf:params:xml:ns:yang:ietf-netconf-monitoring"> <version>2012-02-06</version> <identifier>ietf-netconf-notifications</identifier> <format>yang</format> </get-schema> </rpc>

After debugging on the device side, below is what works correctly on the device side

<rpc message-id="m-25" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <get-schema xmlns="urn:ietf:params:xml:ns:yang:ietf-netconf-monitoring"> <identifier>ietf-netconf-notifications</identifier> <version>2012-02-06</version> <format>yang</format> </get-schema> </rpc>

Basically Identifier should be sent before the versiion. This was also confirmed by tail-f - who pointed to the rfc 6020 - section 7.13 - subsection 7.13.4

Below is the snippet from the ODL log when it fails
