Why a notation is needed Many OSI Applications make use of Distinguished Names (DN) as defined in the OSI Directory [CCI88]. The main reason for having a notation for name format is to interact with a user interface. This specification is coming dangerously close to the sin of standardising interfaces. However, there are aspects of presentation which it is desirable to standardise. It is important to have a common format to be able to conveniently refer to names. This might be done to represent a directory name on a business card or in an email message. There is a need for a format to support human to human communication, which must be string based (not ASN.1) and user oriented. Hardcastle-Kille
