Hi all,
A slight comments on draft-ietf-shim6-proto-05.txt

-Page74
10.1.  Sending Update Request messages
   When a host has a change in the locator set, then it can communicate
   this to the peer by sending an Update Request.

To my understanding, the above stentence state the Update Request 
message (with  Locator List Option, right?) is sent when (or if) the 
locator at the SHIM6 host is changed.
Right?

But It is not clear for me about the "locator change", because the 
situation "locator change" is too general. I think it would be better if 
this draft could provide some examples (cases) about the locator change 
in real applications. For examples, I would like to know if the 
follwoing cases belong to the "locator change" situation described in 
this draft:
-A SHIM6 host is assigned a new usable locator at some interface of the 
SHIM6 host.
-A SHIM6 host finds one of its locators is unusable or failure.

If the above two examples belong to the "locator change" situation, then 
I would like to know if a SHIM6 host must (or can or need to) send the 
Locator Request message with Locator List option to its peers when the 
SHIM6 host is assigned a new usable locator at some interface of the 
SHIM6 host or when the SHIM6 host finds one of its locators is unusable 
or failure.

Cheers,
Deguang
