New description:

 Implement the following per-zone counters into Xfrout regarding
 StatisticsItems:
 ||'''Module'''||'''Item'''||'''in BIND 9 Statistics XML (tree
 representation under isc/bind/statistics)'''||'''Description from BIND 9
 Manual'''||'''Implemented in BIND 10?'''||
 ||Xfrout|| || || || ||
 || ||xfrout.[zonename].notifyoutv4||server/zsstat/NotifyOutv4||Number of
 IPv4 notifies sent from Xfrout||no||
 || ||xfrout.[zonename].notifyoutv6||server/zsstat/NotifyOutv6||Number of
 IPv6 notifies sent from Xfrout||no||
 || ||xfrout.[zonename].xfrrej||server/nsstat/XfrRej||Number of XFR
 requests rejected||no||
 || ||xfrout.[zonename].xfrreqdone||server/nsstat/XfrReqDone||Number of
 requested zone transfers completed||no||

 IMO at least updating three classes(!XfroutServer, !XfroutSession and
 !NotifyOut) is needed  for implementing counters. And adding 'getstats'
 command for returning statistics to the stats module is also needed. A
 dedicated statistics counter class might need to be added. Some test, e.g.
 lettuce scenario, might be needed for testing the increasing values of the
 new Xfrout counters.

Comment:

 Though that fundamental revision is not done yet, I try to add the
 counters based on the current Xfrout codes.
