I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.

The summary of the review is: HAS NITS Re: 9.3 Security Considerations "This prevents an adversary to use a private dictionary..." -> "This prevents an adversary from using a private dictionary..."
