Checksum field

With this field a checksum can be provided for the root-element.

The procedure is identical to the procedure of the checksum property from section 21.3.3 on page .

At this position there are 3 parameters, which are one 16-bit and two 64 bit integers. The first parameter $A$ is the type of checksum. The second parameter $B$ is any number of bits, a checksum should be generated and the third parameter $C$, how many bits the checksum should have. The information applies to the area after the three parameters (even in sub-root-elements). The checksum is implemented as described in section 21.3.3 on page .
