Reviewer: Rifaat Shekh-Yusef Review result: Ready 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. The document defines a YANG data model that defines service configuration elements that can be used in communication protocols between customers and network operators. Those elements can also be used as input to automated control and configuration applications. The authors addressed my comments on version -05 of the document. I have not further comments on this version of the draft. Regards. Rifaat
