BTW, those who recall Schinegger's performance not the ski slopes would dispute your view that no one with an XY DSD could ever perform in sports well enough to give the top-ranked males a run for their money. Because even when he was racing in alpine skiing as a teenager under the name Erika, Schinegger was better not just than all the best girls in the world - Schinegger was better than most of the best guys too.
Schinegger has never revealed the name of his XY DSD, but given that he has fathered a child, it's clearly a DSD that doesn't interfere with the testes' ability to produce viable sperm. So most likely, Schinegger has XY 5-ARD, the DMSD that Semenya has and apparently a number of the other XY DSD athletes in women's sports have.
After he was found to be XY with a male-only DSD in late 1967 whilst preparing for the 1968 Winter Olympics in Grenoble, Schinegger was treated terribly by Austrian ski officials and other honchos in the world of competitive alpine skiing. After taking time off to get therapy to help come to terms with his DSD and getting some kind of surgery to "correct" and "masculinize" his genitals, Schinegger wanted to race in men's alpine skiing - but the Austrian federation and other authorities in the sport wouldn't let him.
Had Schinegger been allowed to race in men's skiing, chances are good he would have swept the gold in all the men's alpine events at the 1972 Winter Games in Japan, just as prior to the discovery of his XY DSD he had been a sure bet to win gold medals in all the women's alpine events at the 1968 Winter Games in France.
