DESCRIPTION
This module handles X.500 RDNs (Relative Distinguished Names). This is a supporting module for X500::DN.Methods
- 
$object = new X500::RDN ('type'=>'value', 'type'=>'value', ...);
Creates an RDN object from argument pairs, each pair an attribute type and value. With more than one pair as arguments, you will get a multi-valued RDN. 
- 
$object->isMultivalued();
Returns whether the RDN is multi-valued. 
- 
$object->getAttributeTypes();
Returns the RDN's attribute types, a list of strings. 
- 
$object->getAttributeValue (type);
Returns the RDN attribute's value. 
- 
$object->getRFC2253String();
Returns the RDN as a string formatted according to RFC 2253 syntax. 
- 
$object->getX500String();
Returns the RDN as a string formatted according to X.500 syntax. NOTE: This is a hack, there is no definition for a X.500 string syntax!? 
- 
$object->getOpenSSLString();
Returns the RDN as a string formatted according to one of openssl's syntaxes. Croaks on multi-valued RDNs.
