Retired in ISO 639-3: Language family name with all constituent languages already represented
Excerpt from change request document:
Land Dayak is a language family name (the current term is actually "Bidayuhic"), rather than a language name. Furthermore, all Bidayuhic (Land Dayak) geographical locations and populations are already accounted for by other Bidayuhic language entries. This entry duplicates geographies and populations, and should be retired.
