# OPSDIR review of draft-ietf-ace-revoked-token-notification-09

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.

The document provides a mechanism for the Authorization Server to notify about revoked access tokens via access to a Token Revocation List (TRL) on the Authorization Server via CoAP. The document is clear and well-written. The motivation is described well. 

I did a review of [-06](https://mailarchive.ietf.org/arch/msg/ace/ElqlgO6FHPsjoqw7L3gKkbSqVUo/) in the past and have now compared the [diff](https://author-tools.ietf.org/iddiff?url1=draft-ietf-ace-revoked-token-notification-06&url2=draft-ietf-ace-revoked-token-notification-08&difftype=--html) with the latest version. The document is ready for publication.

Thanks!
