1.1. vCard fields (NAME, FN, X-AIM, X-JABBER)

Testing was performed on the CardDAV server with two clients accessing the address book. The interpretation of certain vCard fields differed between the clients.

One client incorrectly used the FN and NAME properties, where the FN value was stored in NAME property and the other value shouldn’t have been used at all. Some vCard 4 properties (eg. KIND) were also generated even though the server announced only vCard 3 support.

If custom X-AIM and X-JABBER properties are used for IM information, client cannot understand and resolve them. It is suggested that standard IMPP properties be used instead.
