The proposal is to create and document a simple XML encoding for the responses 
from the Attachment Daemon, to facilitate the use of mobile Management Daemons 
(clients on iPhone, Android, ...)

XML encoding of responses would be completely new.

That's a likely path for a future RFC. A second text (which following the IETF 
process, would have a new number) which corrects and extends the first and which 
is carried along a standards track.  But in the meantime is there a volunteer to 
write text and demonstration code for the current I-D?
