    @ivar rdclass: The class of the rdataset
    @type rdclass: int
    @ivar rdtype: The type of the rdataset
    @type rdtype: int
    @ivar covers: The covered type.  Usually this value is
    dns.rdatatype.NONE, but if the rdtype is dns.rdatatype.SIG or
    dns.rdatatype.RRSIG, then the covers value will be the rdata
    type the SIG/RRSIG covers.  The library treats the SIG and RRSIG
    types as if they were a family of
    types, e.g. RRSIG(A), RRSIG(NS), RRSIG(SOA).  This makes RRSIGs much
    easier to work with than if RRSIGs covering different rdata
    types were aggregated into a single RRSIG rdataset.
