6. Considerazioni IANA

IANA ha allocato i tag nella Tabella 3 usando questo documento come riferimento di specifica. (Il valore riservato è destinato a una futura revisione dei tag per array tipizzati.)

Le allocazioni sono state assegnate dallo spazio "specification required" (24..255) con l’eccezione di 1040, che è stato assegnato dallo spazio "first come first served" (256..).
