RAID-6 wasn't in the original RAID paper, but the term RAID-6 with the
P+Q parity defintion is by far the dominant use of the term, and I
believe it is/was recognized by the RAID Advisory Board, which is as
close as you can get to an official statement. The RAB seems to have
gotten defunct, with a standard squatter page on their previous web
address.
