I asked before as the followings last October in this mailing-list.

|     I have A question about mode parameters of page 0x18 (protocol 
|    specific LUN page) and 0x19 (protocol specific port page).
|
|     In SPC-2 (Rev20) or SPC-3 (Rev00), PROTOCOL IDENTIFIER is
|    described in BYTE 2 on both page 0x18 and 0x19. 
|
|       But in SPI-4, PROTOCOL IDENTIFIER is NOT described (BYTE 2 is
|    reserved) on page 0x18, and is described in BYTE 3 on page 0x19.
|
|       I think SPC is correct, and SPI has typo in description of
|    PROTOCOL IDENTIFIER bits.
|

So, Pinokie-san revised Table 85 in SPI-4 to maintain 
the compatibility for SPC.

Here is his answer at Nov. 1st in this mailing-list.
!Onoyama-san,
!You are correct. SPI-4 has the Protocol Identifier in the wrong byte. I
!will correct it in the next version of SPI-4 if there are no objections
!from anyone. So if anyone has a problem with this change best speak-up
!know.
