The count of SUCCESSFUL 'activations' of reconfiguration for
this host system: invoked by SUCCESSFUL writes to the
'xcmGenReconfOptionState' reconfiguration invocation object of
'activateFor[ImmediateChange|RebootChange|ImmediateReboot]';
and followed by SUCCESSFUL completions of 'activation' (without
errors reports in 'xcmGenReconfError[Index|Status]').
Usage: Although no default value ('DEFVAL' clause) is permitted
(by IETF SMIv2) for this counter, conforming host systems SHALL
zero this counter upon conceptual row creation.
