ietf-netconf-monitoring capability with deviation

We are supporting ietf-netconf-monitoring YANG model but partially, so now we need to advertise the deviation module
in the netconf server capability.
I tried doing it like
<capability>
urn:ietf:params:xml:ns:yang:ietf-netconf-monitoring?module=ietf-netconf-monitoring&deviations=jnx-ietf-netconf-monitoring-dev
</capability>
<capability>
http://yang.juniper.net/yang/1.1/jrpc/jnx-ietf-netconf-monitoring-dev/junos/17.3?module=jnx-ietf-netconf-monitoring-dev
</capability>

but it seems OpenDaylight controller is not taking it as valid capability.
I posted this question on netmod.org mailing list and Andy Bierman confirmed that this is syntactically correct.

Am i missing something here ?
