A question regarding the notes in 10 and 11:

Would it make more sense to suggest that the mail system make the 
UAID clear to the reader if its the identity whose reputation was 
used to deliver the message, and make the SDID clear to the reader 
otherwise?


Simple question:  why?

Complex question:  What is the empirical basis for believing that any 
user interface design recommendations that we make will have any 
utility to the end-user?  Experience with usability design 
demonstrates a key constant:  it is almost impossible to ensure user 
interface utility in the absence of empirical data.

Simple answer: If the purpose of the original text was to point out to 
users who the message is really from in cases of suspected forgery, and 
through whatever means the receiving system has decided that the real 
responsible identity is the UAID and not the SDID , it seems to me to 
fit better with the original intention of showing the user who the 
message is really 'from' to point out the UAID.

Complex answer:  I agree with the observation and don't know that there 
is any.  Is there a purpose for changing these sections beyond 
consistency with the rest of the document?
