Document: draft-ietf-precis-7564bis-07 Reviewer: Matthew A. Miller Review Date: 2017-06-13 IETF LC End Date: 2017-06-13 IESG Telechat date: 2017-07-06 Summary: This document is ready to be published as a Standards Track document. This document defines a framework application protocols use to prepare, compare, and enforce conformance of internationalized strings. It obsoletes RFC 7564. This document is well written, and reinforces the security concerns discussed in Section 12 with references in the most relevant sections throughout the document. While much of it essentially proclaims "be aware herein be dragons", the arguments for not proscribing more are well laid out. Major Issues: NONE Minor Issues: NONE Nits: NONE
