See ``dns.name.Name.choose_relativity`` for more information on how *origin* and *relativize* determine the way names are emitted. Any additional keyword arguments are passed on to the rdata ``to_text()`` method. *name*, a ``dns.name.Name``. If name is not ``None``, emit RRs with *name* as the owner name. *origin*, a ``dns.name.Name`` or ``None``, the origin for relative names. *relativize*, a ``bool``. If ``True``, names will be relativized to *origin*. *override_rdclass*, a ``dns.rdataclass.RdataClass`` or ``None``. If not ``None``, use this class instead of the Rdataset's class. *want_comments*, a ``bool``. If ``True``, emit comments for rdata which have them. The default is ``False``.

If ``None`` (the default), names will not be compressed. *origin* is a ``dns.name.Name`` or ``None``. If the name is relative and origin is not ``None``, then *origin* will be appended to it. *override_rdclass*, an ``int``, is used as the class instead of the class of the rdataset. This is useful when rendering rdatasets associated with dynamic updates. *want_shuffle*, a ``bool``. If ``True``, then the order of the Rdatas within the Rdataset will be shuffled before rendering. Returns an ``int``, the number of records emitted.
