I have one question on sec 5.4 before I enter a comment...

It took me a couple readings of 5.4 to THINK I understand fig 7.

I THINK this occurs after Mobile Host has sent its HIP UPDATE with the 
new locator information.

I believe the implication of this figure is that the stationary node 
(peer host) sends its address validation HIP UPDATE and instead of 
receiving the HIP UPDATE with ACK, it receives actual data which it may 
interpret as the ACK.

So I have two points.

First does this only apply when there are new SPI?  What about a move 
with no SPI changes?

Second, the actual figure should include the original HIP UPDATE from 
Mobile Host to make it clear the nature of the mobility.

Sorry for the late review of this draft.

I can submit an official comment if others think my questions raise 
clarity issues.
