    Hi Thomas and PAYLOAD participants:
    
    What do you think; is the errata report correct? Seems like it is borderline between editorial and technical.
    
    Thanks!
    
    Ben.

The values in Figure 1 for the Data_Count fields do not have the correct parity bits according to the definition of Data_Count described in section 2.1.
