With the current 'shall' wording the target is required to place a zero in
the data length field of the L_Q IU. As a result there is no Status IU
sent. This allows better performance because needless information (i.e., a
bunch of zeros in the Status IU to indicate a good completion) is not
transferred. The problem is; in a few cases, even though status is zero
there may be information that needs to be sent in the Status IU that is
currently not allowed because of the 'shall'. Placing a 'should' at that
point fixes the problem.

Bye for now,

What is the reason for changing "shall" to should"?
