Hi Kristian
Thanks for the explanation.
I don’t think we need to respin the draft.
After reading the text again both the old and new are close to the same so I am good with progressing the draft.
Thank you
Gyan

Hi Gyan,
thanks Mahesh for the explanation, it’s exactly right. We don’t update the HTTP spec at all, we borrow its concepts and apply them to netconf. The w3c trace context headers are sent as XML attributes for NETCONF.
I don’t understand the minor issue you list Gyan. What about port 830, SOAP 832 & 833? Regardless if NETCONF is over SSH, TLS, SOAP (in turn over BEEP or HTTPS), it still sends XML encoded RPCs and the trace context XML attributes are encoded in there. I don’t think we need to explicitly mention or deal with the details of the lower layer transports!?
The abstract changes read very similarly to me, do you really think this warrants another spin at this point?
Kind regards,
Kristian.
