I believe Azlina is correct. What should we do to resolve?

Jean-Francois,
I believe we have extended the upper bound of a mib object
in the past :)
However, per RFC2578 Section 9 rule (3) defined that "the size in octets
of the value may be refined by raising the lower-bounds, by reducing the
upper-bounds, and/or by reducing the alternative size choices."
So, extending this size may not be permitted.
Thanks,
Azlina
