Hello, I have reviewed draft-amundsen-item-and-collection-link-relations as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This draft adds two new kinds of web links for "item" and "collection" to allow web resources to identify a relationship as part of a collection and, back the other way, for the collection to identify items that comprise it. Web links were defined in RFC 5988 and that document has a nice Security Considerations section. I see no security issues with this draft that would warrant any special mention and the Security Considerations of this draft basically state that. My only nit is to get rid of the passive voice in the Security Considerations, that is: 's/are not believed to/do not/'. regards, Dan.
