# OPSDIR review of draft-ietf-anima-jws-voucher I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in the last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last-call comments. Thanks for working on this document. It's clear to me, and I don't have any comment from operational point of view. Thanks, Yingzhen
