G'Day Troy,

Yes that's correct. I'll add the following text to the proposed
implementor's guide additions.
1.5 Optional Statistics Parameter Value + Binary

Description:    In section 7.2.6 for Audit capability its stated that
"StatisticsDescriptor returns the names of the statistics being kept on
the termination."
But the ABNF grammar states the descriptor as "statisticsDescriptor =
StatsToken LBRKT statisticsParameter *(COMMA statisticsParameter ) RBRKT
;at-most-once per item
statisticsParameter  = pkgdName EQUAL VALUE"
which doesn't allow specification of stats parameter always with value.
If only names needs to be sent from MG, the value field needs to be made
option.
This updates Implementors' guide section 6.25 which the addition of the
change to the binary protocol.
