Robert, thanks for your review. I managed to ballot before reading the rest of this thread (sorry!), but I still think the diagram in 4.3 is confusing and not consistent with the text. To my eye row 3 shows two bytes’ worth of fields but the label says “4 bytes.” RSV is depicted as 2 bits but the text says it is 6 bits. The combination of these two inconsistencies makes it hard to know what the actual lengths are supposed to be.
