 Right now, it's hardcording some default values, which just happen to
 be consistent with the spec file:

 {{{
 class MockCC():
     def get_default_value(self, identifier):
         # The returned values should be identical to the spec file
         # XXX: these should be retrieved from the spec file
         # (see MyCCSession of xfrout_test.py.in)
         if identifier == "zones/master_port":
             return TEST_MASTER_PORT
         if identifier == "zones/class":
             return TEST_RRCLASS_STR
         if identifier == "zones/use_ixfr":
             return False
 }}}

 Obviously it's ugly and more difficult to maintain.  As commented the
 mock class should retrieve the defaults from the spec file.  We should
 also have some tests to check whether the default values are really
 used in other cases (such as "max transfer in").
