Hi Qin,

I think that you may have accidentally removed the RFC editor instructions in the YANG module that presumably we want to still keep?

	 	// RFC Ed.: update the date below with the date of RFC publication	
 	      // and remove this note.	
 	      // RFC Ed.: replace XXXX with actual RFC number and remove this	
 	      // note.

For the update to the security section, my concern wasn't so much about no longer being able to access a private key, but more that a client cannot rely on any private data being unrecoverable after the factory-reset RPC.  I.e. they can't just use the factory-reset RPC and then sell the device on ebay, with the assumption that all private data has been properly cleansed.

OLD:

	
 	   The non-volatile storage is expected to be wiped clean and reset back	
 	   to the factory default state, but there is no guarantee that the data	
 	   is wiped according to any particular data cleansing standard, and the	
 	   owner of the device MUST NOT rely on any temporary data (e.g.,	
 	   including private keys) for recovery after the factory-reset RPC has	
 	   been invoked.

NEW:

	
 	   The non-volatile storage is expected to be wiped clean and reset back	
 	   to the factory default state, but there is no guarantee that the data	
 	   is wiped according to any particular data cleansing standard, and the	
 	   owner of the device MUST NOT rely on any sensitive data (e.g.,	
 	   private keys) being forensically unrecoverable from the device's
          non-volatile storage after a factory-reset RPC has been invoked.

Thanks,
Rob
