In table C.2 (part 2 of 6) on page 475, the READ CAPACITY command
(opcode 25h) is not listed as being mandatory for RBC devices.
I believe this to be an omission based on section 5.3 of the rbc-r10a
PDF.  Could this be corrected?

"Bill, look, we understand that you're interested in selling us this
operating system, but compare it to ours.  We can't possibly take such
a retrograde step."
