Thanks Anders for the comment. Having said that, I do not know how to 
act on it.
As far as signHTTP is concerned, what I have on the comment sheet seems 
to be pretty much we can reasonable write as the working group.  Many 
people do not understand the difference between different tracks of RFC 
and the difference between the individual drafts and IETF drafts. So, 
the comment is pointing it out.

I have tried to put the collected comments on the comment sheet.
We are going to send it off tomorrow, so please review it asap.
