IMO this needs to be YANG Patch because it is more precise then constructing an XML tree with operation attributes in it (e.g., how else do you represent a delete or a move?) Also, YANG Push is using YANG Patch format and common code for push and diff would be possible. I think other formats should be allowed. This is very tool-specific. I could see how somebody might want a textual patch of the XML representation to produce the new XML representation. > /js > Andy > > On Thu, Oct 04, 2018 at 05:41:22PM +0000, Kent Watsen wrote: > > We agree that the diff-format should be client-selectable, modulo what > the server supports. yang-patch and edit-config both are viable.
