Application Family Identifier (AFI)

The AFI represents the type of application targeted. AFI is coded on one byte,
which constitutes two nibbles of 4 bits each. The most significant nibble of AFI
is used to code one specific or all application families, as defined in the table
below. The least significant nibble of AFI is used to code one specific or all
application sub-families. Sub-family codes different from 0 are proprietary.
