The relevance of this tweak to the Unacknowledged CFDP Extensions may not 
be obvious, but I think it is real.  By turning off Notice of Completion 
issuance on receipt of EOF in Unacknowledged mode when the file is not 
completely received, UCE disables delivery of the Finished indication under 
these conditions.  It is possible that some CFDP implementations might 
count on that indication to signal EOF arrival in Unacknowledged mode 
(regardless of file delivery completeness), for purposes similar to those 
Tim describes; UCE would break those implementations.  By adding an 
optional EOF-Received indication we could provide a replacement source for 
this information without working too hard.

I definitely DO NOT want to open the door to casual reconsideration of CFDP 
specification elements in general.  But I think the UCE revisions do 
arguably motivate Tim's proposed mod, and I think the impact of the change 
would be modest.  Let's discuss on this list and at the UCE working group 
meeting in Montreal.
