Re: [netconf] Capability-fetching mechanisms

Hi Qin, Alex, Qiufang,

Mahesh and I generally agree with the idea of a common response payload format that could be conveyed via draft-specific transports.  We further understand that there is a proposal to use the YANG Instance File Format as the common format.  However, we do not yet fully understand what the response might look like for the “https-notif” draft were it to use the YANG Instance File Format.   Could one of you send an example of what that response might look like matching the contents of the example found in Section 3.4 in the "https-notif” draft?
