+1.

I actually wonder whether extending RESTCONF wouldn't be a more 
efficient path here.  Adding support for CBOR to RESTCONF looks like it 
would be much easier than adding it to NETCONF.

But then, it is unclear to me what the long term relationship between 
NETCONF and RESTCONF is meant to be.

Thanks,
