I have reviewed this document as part of the Ops area directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Ops area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The document describes adding attributes to indicate a call has been diverted from its original destination to a new one. the document is written very clear. IMHO, it would be nice not to let any call originator hide his/her information, so that we can see much smaller number of spam calls. Best regards, Linda Dunbar
