Most folk convert from crab to wing down in the last 50 ft or so. Wing down is where you drop the into wind wing and keep the aircraft straight with rudder so the controls are crossed. This is better for gusty conditions if you are quick enough with aileron and rudder to keep to the centre line in the round out and flare.
Do it well and you land one wheel at a time!
By the way "Max demonstrated crosswind" isn't a limit, it is what was demonstrated on the approval flight. Most light aircraft can cope with more than that, the limit being rudder authority.
