    - #### RDN

          public RDN(ASN1ObjectIdentifier oid,
                     ASN1Encodable value)

      Create a single valued RDN.
      Parameters:
        `oid` - RDN type.
        `value` - RDN value.

    - #### RDN

          public RDN(AttributeTypeAndValue attrTAndV)

    - #### RDN

          public RDN(AttributeTypeAndValue[] aAndVs)

      Create a multi-valued RDN.
      Parameters:
        `aAndVs` - attribute type/value pairs making up the RDN
