A table of notification rules (recipient/event lists)
registered for event delivery from this host system.
Note: In this MIB, the term 'notification rule' is equivalent
to the term 'Subscription object' in IPP Notifications.
Usage: Conforming management agents SHALL NOT accept sets to
any other columnar object in 'xcmGenNotifyRuleTable' when
'xcmGenNotifyRuleRowStatus' is 'active'.
Dynamic rows must be deleted (with 'destroy') and then recreated
(with 'createAndGo') with new columnar values.
Static rows must be released (with 'notInService') and then
then reallocated (with 'active') with new columnar values.
Thus only a row status transition to 'active' indicates a new
notification registration by a conforming management station.
Usage: Conforming management agents SHALL delete any
rows in the 'xcmGenNotifyDetailTable' which were subordinate to
a deleted row in the 'xcmGenNotifyRuleTable'.
