6. IANA-Erwägungen

IANA hat die Tags in Tabelle 3 unter Verwendung dieses Dokuments als Spezifikationsreferenz zugewiesen. (Der reservierte Wert ist für eine zukünftige Überarbeitung der Tags für typisierte Arrays vorgesehen.)

Die Zuweisungen stammen aus dem Bereich „specification required“ (24..255), mit Ausnahme von 1040, das aus dem Bereich „first come first served“ (256..) zugewiesen wurde.
