The -05 draft is considerably better written than the earlier drafts, but it still lacks what I think is a critical explanation: A description of what a given History-Info header means. The draft gives a series of procedures, but there's no way to check whether they are correct or not, because there's no way to say whether their results are correct. It's like trying to check the correctness of an algorithm when there's no specification of the desired output. I'll write a draft of such a thing this weekend. Dale
