The LocaleIds,with DataType LocaleId,defines a list of locale ids in priority order for localized strings for all DataSetWritersin the WriterGroup. The first LocaleIdin the list has the highest priority.

If the Publishersends a localized String, the Publishershall send the translation with the highest priority that it can. If it does not have a translation for any of the locales identified in this list, then it shall send the Stringvalue that it has and include the LocaleIdwith the String. If no locale id is configured, the Publishershall use any that it has. See OPC 10000-3for more detail on LocaleId.
