It may be a ``dns.name.Name``, a ``str``, or ``None``. If ``None``, then the zone's origin will be set by the first ``$ORIGIN`` line in a zone file. *rdclass*, an ``int``, the zone's rdata class; the default is class IN. *relativize*, a ``bool``, determine's whether domain names are relativized to the zone's origin. The default is ``True``. *pruning policy*, a function taking a `Version` and returning a `bool`, or `None`. Should the version be pruned? If `None`, the default policy, which retains one version is used.

The *policy* function takes a `Version` and returns `True` if the version should be pruned, and `False` otherwise. `None` may also be specified for policy, in which case the default policy is used. Pruning checking proceeds from the least version and the first time the function returns `False`, the checking stops. I.e. the retained versions are always a consecutive sequence.
