I think the IBJJF is being more open minded? I had 10th Planet Peers get DQ'd for Electric Chair or Crotch Ripper submissions in years past, but the new and improved and much-needed-of-an-update 2012 IBJJF rule book (now in PDF format!) states you can stretch the legs apart. I always remember this being prohibited before. Only the kids cannot submit by stretching the legs apart.
Also, the rule book now includes accompanying photos.
