AbsoluteCounter32 ::= TEXTUAL-CONVENTION
        STATUS current
        DESCRIPTION
               "Represents a Counter32-like value that starts at zero,
                does not decrease, and does not wrap. This may be used
                only in situations where wrapping is not possible or
                extremely unlikely. Should such a counter overflow,
                it locks at the maxium value of 4,294,967,295.

                The primary use of this type of counter is situations
                where a counter value is to be recorded as history
                and is thus no longer subject to reading for changing
                values."
