The rules are, they must end with START/END 34 * The proper convention is incrementing a number like so: 35 * AID_OEM_RESERVED_START 36 * AID_OEM_RESERVED_1_START 37 * AID_OEM_RESERVED_2_START 38 * ... 39 * The same applies to the END. 40 * They are not required to be in order, but must not overlap each other and 41 * must define a START and END'ing range.
