    == COMMENTS ==

    If the "factory-default" is optional (per section 3), then it may be worth to specify this quality in the abstract and in the introduction.

    [Qin]: Thanks, will mention this in both abstract and introduction.

    -- Section 2 --
    What happens with the different counters in the <operational> data store ?


    [Qin]: As described in 2, The contents of the <operational> datastore MUST reflect the
    operational state of the device after applying the factory default
    configuration. In other words, Referencing figure 2 of RFC8342, counter seen as system state of operational datastore will reflect
    the operational state of the device. 

    Why is this a SHOULD for overwritting sensitive data before deletion and not a MUST? At least section 6 writes that "owner of the device MUST NOT rely on any sensitive data (e.g., private keys) being forensically unrecoverable"

    [Qin]: I have no preference on whether we should use strong language or soft language, but the idea here is deleting dynamically generated files is mandatory, overwriting security sensitive data is recommended.
