WG, I have helped Philip and Marshall to get an updated version addressing the WG last call comments submitted. This version addresses mine and Gorry's comments to the mailing list earlier this year. During the editing and subsequent review Gorry spotted an additional document structure issue with normative text in a discussion section. To address these a bit more changes where needed. As can be seen in the diff there is quite a number of changes:
http://www.ietf.org/rfcdiff?url2=draft-ietf-6man-udpchecksums-03 Based on that there some changes to the formulation of normative statements, although not their spirit, I request that the WG chairs do initiate a last call on this new version to confirm the WG's desire to request publication of this version. Considering that a number of I-Ds have dependency on this document I would request that the people interested in those I-Ds do review this.
