Hi Qin,

Section 2:
* "All security sensitive data (i.e., private keys, passwords, etc.)  SHOULD be 
overwritten ..." presents a choice.  Why would an implementer not do this? *
[Qin]: This was outcome of the discussion, see the following link:
https://mailarchive.ietf.org/arch/msg/netmod/qrU_71AkP42lnkR6KnfaMsoSgCs/
i.e., folks concerned to restore security data and password to default value, 
that's we introduce clean requirements to address this concern.
"Implementors SHOULD reboot the device or otherwise restart processes needed to 
bootstrap it." leads me to the same question.
[Qin]: To make default configuration take effect, the device reboot is 
recommended, but in some case, the IP address reachability of the device may be 
lost, therefore bootstrapping may be needed.

For both of these I suggest mentioning in the document the reason it's a SHOULD 
and not a MUST, i.e., describe a situation when it might be okay to do 
something other than what it says.

(Reminder: These are not blocking comments, just suggestions.)

Thanks for considering these suggestions.
