OTPCounterBasedGauge64 ::=
--TEXTUAL-CONVENTION
--   STATUS       mandatory
--   DESCRIPTION
--         "The CounterBasedGauge64 type represents a non-negative
--         integer, which may increase or decrease, but shall never
--         exceed a maximum value, nor fall below a minimum value. The
--         maximum value can not be greater than 2^64-1
--         (18446744073709551615 decimal), and the minimum value can
-- 
--         not be smaller than 0.  The value of a CounterBasedGauge64
--         has its maximum value whenever the information being modeled
--         is greater than or equal to its maximum value, and has its
--         minimum value whenever the information being modeled is
--         smaller than or equal to its minimum value.  If the
--         information being modeled subsequently decreases below
--         (increases above) the maximum (minimum) value, the
--         CounterBasedGauge64 also decreases (increases).
-- 
--         Note that this TC is not strictly supported in SMIv2,
--         because the 'always increasing' and 'counter wrap' semantics
--         associated with the Counter64 base type are not preserved.
--         It is possible that management applications which rely
--         solely upon the (Counter64) ASN.1 tag to determine object
--         semantics will mistakenly operate upon objects of this type
--         as they would for Counter64 objects.
-- 
--         This textual convention represents a limited and short-term
--         solution, and may be deprecated as a long term solution is
--         defined and deployed to replace it."
