        I{relation} describes the relation ship beween the names,
        and is one of: dns.name.NAMERELN_NONE,
        dns.name.NAMERELN_SUPERDOMAIN, dns.name.NAMERELN_SUBDOMAIN,
        dns.name.NAMERELN_EQUAL, or dns.name.NAMERELN_COMMONANCESTOR

        I{order} is < 0 if self < other, > 0 if self > other, and ==
        0 if self == other.  A relative name is always less than an
        absolute name.  If both names have the same relativity, then
        the DNSSEC order relation is used to order them.

        I{nlabels} is the number of significant labels that the two names
        have in common.
