The IETF is working on an updated AES key warpping mechanism with  
padding:

> http://www.ietf.org/internet-drafts/draft-housley-aes-key-wrap-with-pad-00.txt

Russ Housley's advice (and request) is to coin a new URI for use of  
this algorithm with XML Encryption; we have a URI for the previous AES  
key wrap mechanisms.

I suggest that we do that for XML Encryption 1.1.  From what I  
understand, it's likely that this draft will be have an RFC number  
within very few months, i.e., we shouldn't have a problem referencing  
it.

My suggestion would be something along the lines of:

   http://www.w3.org/2009/xmlenc#kw-aes128-padded (REQUIRED)
   http://www.w3.org/2009/xmlenc#kw-aes192-padded (OPTIONAL)
   http://www.w3.org/2009/xmlenc#kw-aes256-padded (REQUIRED)

... using (for the moment) draft-housley as the reference.

While there is no huge amount of urgency to this, I suspect that  
feeding back the URIs would also be useful for other efforts like  
keyprov.  Phill, you know more about that one...
