Now that were in Last Call -> CR transition, does anyone know where we 
stand on AES key wraps?

Note: XML Encryption does NOT provide an on-line key agreement negotiation 
protocol. The key agreement structure defined here is only suitable for 
off-line agreement. Agreement based, for example, on trusted recipient key 
information obtained previously from some public key infrastructure by the 
originator. If a key has been agreed to via some previous on-line protocol, 
it would be more natural to use a KeyName or the like to refer to an agreed 
name. 

How would you define/distinguish a previous online and previous offline 
method?
