I have reviewed this document as part of the security directorate’s ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This document defines a media type for a YANG-based editing mechanism that can be used with the HTTP PATCH method. I agree that this mechanism does not introduce any new security issues,  beyond what is described in [I-D.ietf-netconf-restconf]. So, this draft is almost ready for publication.  A question: In Section 2.6  you mentioned 'The server will save the running datastore to non-volatile storage' . Do you assume the severs supporting your mechanism always have non-volatile storage?
