I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. Document editors and WG chairs should treat these comments just like any other comments. This draft sets forth changes to the syntax of Enrollment over Secure Transport (EST) (RFC7030) to fix some errors and ambiguities that resulted in interoperability issues. RFC7030 also includes a form of header that has been deprecated in other RFC’s. This document thus deprecates that header as well. Since the only changes to the draft makes to the syntax are either to clarify ambiguities in the descriptions and to deprecate syntax that has already deprecated by other RFC’s, it presents no new security or privacy concerns. However, I found a few typos, etc. that I am listing below. They are all of the sort that would be missed by a spell checker. I don’t know if I got all of them, so I’d suggest another round or proofreading. I consider this document Ready with Nits.
