TOI may be omitted for A flag packets with FLUTE (and also for a single object transfer with ALC). LCT says TOI + TSI filed must be 32 bit aligned. TSI may be 16, 32 or 48 bits length. Thus, the TOI field may not be omitted for objects in sessions with TSI lengths of 16 or 48 bits. (for 16 bits, the TSI can be increased to 32 bits just for A flag packets without TOI by switching S, O, H flags - but this is not desirable and doesn't work for 48bit TSI).
Should we add a note to LCT (and/or ALC) that "Omitting the TOI field is only feasible for packets with 32 bit TSI field length."?
BTW, an implementation option is to set TOI = 0 for A flag packets where TSI is 16 or 48 bits length
