Document: draft-ietf-calext-rscale-04 Reviewer: Robert Sparks Review Date: 03-03-2015 IETF LC End Date: 03-03-2015 IESG Telechat date: 03-05-2015 Summary: Ready modulo one nit This draft reads easily (describing the actual work converting between calendars is hard, but this draft doesn't have to talk about that). The body of the draft says it updates 5546 and 4791, but those are not listed in the Updates: line in the header?
