Did Pius XII keep baptized Jewish babies from their parents?

An article in the latest The American magazine tries to answer a recent objection posed to the beatification process for Pius XII:

"The latest controversy began on Dec. 28, 2005 when Alberto Melloni, an Italian scholar and the co-director of the John XXIII Center in Bologna, published an article in Corriere della Sera reporting the existence of a 1946 document in which the pope told Monsignor Angelo Roncalli, the papal nuncio in France and future Pope John XXIII, that the Church should keep custody of baptized Jewish children. News agencies immediately picked up the story, giving it global reach."

"A copy of the document that Melloni discovered was leaked to The New York Times and published in translation on its web site on Jan. 9. It states that baptized Jewish children should not be turned over to Jewish agencies that would not be able to guarantee their Christian upbringing, and that such children should also be withheld, even if their parents ask for them. A notation at the bottom of the document reads that this decision "has been approved by the Holy Father [Pius XII]."

But did he really approve this decision? Read on!

(I'm sure the Society That Thinks Pope Pius XII Rules will be interested in the answer, and the article.)

Oh, and since I've already posted one huge picture, here's another:
