=item * $object = new X500::RDN ('type'=>'value', 'type'=>'value', ...);

With more than one pair as arguments, you will get a multi-valued RDN.

=item * $object->isMultivalued();

Returns whether the RDN is multi-valued.

=item * $object->getAttributeTypes();

Returns the RDN's attribute types, a list of strings.

=item * $object->getAttributeValue (type);

Returns the RDN attribute's value.

Returns the RDN as a string formatted according to RFC 2253 syntax.

=item * $object->getX500String();

NOTE: This is a hack, there is no definition for a X.500 string syntax!?
