Backends should not do any thinking about wildcards, and only answer
with a wildcard if queried for one explicitly.

You should be setting the 'zone ID' field in the answers your PIPE
backend provides. The AXFR query you'll get is for that zone ID
number. So make sure you have a unique number per zone.

Good luck!
