+Feature: IXFR out
+    Tests for IXFR-out, specific for BIND 10 behaviour.
+    These are (part of) the tests as described on

+
+    Scenario: Test Set 1
+        Given I have bind10 running with configuration ixfr-out/testset1-config.db

+        # Once we implement it, we can uncomment them. The tests themselves
+        # should already work
