Summary: This document is nearly ready for publication as a Proposed 


Standard




Major issues:

Minor issues:


    The requirements discussions for redirection and referral (second 


paragraph of section 3, in regards REQ-3) includes what appears to be 


normative requirements on redirecting devices.



a) This would seem to belong in section 4 on Normative Definition.


b) It would seem that there ought to be some discussion of what happens 


with redirecting devices that do not understand this new UUI. (I presume 


things work, but I don't see how.)




Nits/editorial comments:


    In section 8.2, given that this is a WG document, should the "the 


authors believe" actually be "the WG believes"?  Or even, given IETF 


rough consensus on this document, "the IETF believes"?
