Vince, This is my first post to the PAWS list (and indeed any IETF draft) so please let me know if I'm not following procedure.
I'm glad draft 04 covers database discovery in more detail. I'm still curious about the Error Handling section. I understand a grace period is useful and necessary when no databases are contactable by the Device for a short period. Does this also handle the scenario of the Device losing contact with the regulatory domain's Listing Server? Should Devices trying to update their database entry from a Listing Server which has gone away have a grace period/hold timer too? Or does the first failed attempt cause complete shutdown of the Device?
