Section 3.3.2 says:

o Transfer Length (F): 40-bit unsigned integer. A non-negative integer that is at most 946270874880. This is the transfer length of the object in units of octets. ... NOTE: The limit of 946270874880 on the transfer length is a consequence of the limitation on the symbol size to 2^^16-1, the limitation on the number of symbols in a source block to 56403, and the limitation on the number of source blocks to 2^^8.

It should say:

o Transfer Length (F): 40-bit unsigned integer. A non-negative integer that is at most 942574504275. This is the transfer length of the object in units of octets. ... NOTE: The limit of 942574504275 on the transfer length is a consequence of the limitation on the symbol size to 2^^16-1, the limitation on the number of symbols in a source block to 56403, and the limitation on the number of source blocks to 2^^8-1.

Notes:

Section 3.3.3 defines the number of source blocks (Z) as an unsigned 8-bit integer, whose maximum value is 2^^8-1 (255), and not 2^^8. This in turn changes the limit on the transfer length, which is now 56403*(2^^16-1)*(2^^8-1) = 942574504275.
