According to the standards, this revision number is:

SFF-8035i rev 1.0 (1995): "0x0004 for this spec revision"
SFF-8035i rev 2.0 (1996): "0005h for this spec revision"
ATA 3 rev 7b (1997): "0x0004 for this revision"
ATA 4 rev 18 (1998): "Vendor specific"
... (ATA 5, 6, 7, ACS, ACS-2) ...
ACS-3 rev 5 (2013) : "Vendor specific"

Unfortunately this revision number is as vendor specific as the whole 
SMART attribute data structure (bytes 0-361 of SMART data structure).

Thanks,
