Folks: 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 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.   This draft discusses Guidelines and Registration Procedures for URI Schemes. It looks Operations and Management Review Checklist defined in RFC5706 doesn't apply since there is no new protocol or protocol extension defined in this draft. I think this draft is ready for publication. Here are a few editorial comments:   1.        Section 1, last two paragraphs s/Interationalized/Internationalized s/accomodate/accommodate 2.        Section 1, last two paragraphs It looks these two paragraphs more fit into Scheme definition requirements section, why split it out from section 3? would it be good to incorporate these two paragraphs into section 3, No,?   3.        Section 3, the 6 th paragraph said: “ The URI scheme name registration procedure can be used in such an event. ” Pointing to section 7 would be good.   4.        Section 4 and 5 Are there guidelines for permanent URI Scheme Registration if there is permanent URI Scheme Registration? Or Permanent URI Scheme Registration can only be possible by upgrading provision URI Scheme Registration?   -Qin
