Hello Katata-san,
The T10 CAP working group considered your 'Consulting item' today and they
have agreed to change item c) in the first list within section 5.12.1 Power
management overview as follows:
 c) commands that manage power conditions (e.g., a START STOP UNIT command in
SBC-3 or MMC-6);
The change is the addition of 'or MMC-6'. This will appear in SPC-4 revision
Hopefully, this will help readers find the sleep information in MMC.
Best regards,
