Review draft-leibzon-content-author-originator-00.txt

I'd like to request review of my recently published draft:
  http://www.ietf.org/internet-drafts/draft-leibzon-content-author-originator-00.txt
  http://www.elan.net/~william/emailsecurity/draft-leibzon-content-author-originator-00.html

The draft proposes two new header fields Content-Author and Content-Originator
for use with specific message data parts (note: 'message' is not limited 
to SMTP as HTTP transmission is considered valid message) and identification 
of the author of the data content and person responsible for originating 
transmission of the data part. Examples in the draft are good illustration
of what I mean.

I'd like to also receive comments as to the security considerations that 
should be mentioned (if any) as I do not believe my current text is 
sufficient or appropriate.
