Per the CAP WG discussion of 04-171, I plan to submit a letter ballot
comment on SBC-2 making these changes:

a) change READ (6) and READ (10) from mandatory to optional in 
table 12 and in note 9

b) change READ CAPACITY (10) from mandatory to optional in table 12

c) mark each of these commands as mandatory if any of their smaller
counterparts are implemented (the same rule that currently 
exists for WRITE (16)): 
    LOCK UNLOCK CACHE (16)
    PRE-FETCH (16)
    READ DEFECT DATA (12)
    READ LONG (16)
    SYNCHRONIZE CACHE (16)
    VERIFY (16)
    WRITE AND VERIFY (16)
    WRITE LONG (16)
    WRITE SAME (16)
    XDREAD (32)
    XDWRITE (32)
    XDWRITEREAD (32)
    XPWRITE (32)
