    the rrset.  If not ``None``, then the owner name is "forced", and the
    input must not specify an owner name.  If ``None``, then any owner names
    are allowed and must be present in the input.

*ttl*, an ``int``, string, or None.  If not ``None``, the the TTL is
    forced to be the specified value and the input must not specify a TTL.
    If ``None``, then a TTL may be specified in the input.  If it is not
    specified, then the *default_ttl* will be used.

*rdclass*, a ``dns.rdataclass.RdataClass``, string, or ``None``.  If
    not ``None``, then the class is forced to the specified value, and the
    input must not specify a class.  If ``None``, then the input may specify
    a class that matches *default_rdclass*.  Note that it is not possible to
    return rrsets with differing classes; specifying ``None`` for the class
    simply allows the user to optionally type a class as that may be convenient
    when cutting and pasting.

*default_rdclass*, a ``dns.rdataclass.RdataClass`` or string.  The class
    of the returned rrsets.

*rdtype*, a ``dns.rdatatype.RdataType``, string, or ``None``.  If not
    ``None``, then the type is forced to the specified value, and the
    input must not specify a type.  If ``None``, then a type must be present
    for each RR.

*default_ttl*, an ``int``, string, or ``None``.  If not ``None``, then if
    the TTL is not forced and is not specified, then this value will be used.
    if ``None``, then if the TTL is not forced an error will occur if the TTL
    is not specified.

*idna_codec*, a ``dns.name.IDNACodec``, specifies the IDNA
    encoder/decoder.  If ``None``, the default IDNA 2003 encoder/decoder
    is used.  Note that codecs only apply to the owner name; dnspython does
    not do IDNA for names in rdata, as there is no IDNA zonefile format.

*origin*, a string, ``dns.name.Name``, or ``None``, is the origin for any
    relative names in the input, and also the origin to relativize to if
    *relativize* is ``True``.

*relativize*, a bool.  If ``True``, names are relativized to the *origin*;
    if ``False`` then any relative names in the input are made absolute by
    appending the *origin*.
