The DisplayName Attribute contains the localised name of the Node. Clients should use this Attribute if they want to display the name of the Node to the user. They should not use the BrowseName for this purpose. The Server may maintain one or more localised representations for each DisplayName. Clients negotiate the locale to be returned when they open a session with the Server. Refer to OPC 10000-4 for a description of session establishment and locales. Subclause 8.5 defines the structure of the DisplayName. The string part of the DisplayName is restricted to 512 characters.
