Document: draft-ietf-regext-bundling-registration-09 Reviewer: Joel Halpern Review Date: 2019-03-07 IETF LC End Date: 2019-03-15 IESG Telechat date: Not scheduled for a telechat Summary: This document is almost ready for publication as some form of RFC Major issues: This document defines protocol extensions and mandatory procedures to go with them. As such, it seems it is either Experimental or Proposed Standard, but not Informational. Minor issues: Section 5 consists of a list of behavioral requirements that appear normative, but do not use RFC 2119 language. If these are indeed normative behavioral requirements, the document should use RFC 2119 language to be clear. (And therefore, should also include the text explaining and citing RFC 2119.) The description in 7.2.1 of the EPP command seems lacking. After saying that it needs an extension element, it says: The element SHOULD contain a child element that identifies the bundle namespace and the location of the bundle name schema. It is unclear when it is reasonable to omit this element. (We normally include with "SHOULD" explanations of this sort.) It is unspecified what format of the information in the element has. I suspect that it is assumed to be the same as some other piece of EPP information, but it does not say so. The only child element for given in the schema is the which is neither a namespace identifier nor a location of the bundle name schema. Again in 7.2.2 on the EPP command, when discussing the addition to the response, it is a SHOULD with no explanation of when it is okay to omit it. The same applies to the 7.2.3 EPP command, the 7.2.4 EPP command, and the 7.2.5 EPP command. Nits/editorial comments:
