I looked it up, and see what you mean. 

Despite the description given, it is my understanding from a study day on the women diaconate with a half dozen scholars, that the actual work was done by two men. The first produced a report, which was not accepted; so they had another one done. If correct, then the intro text in the published report is understandable fig leaves.

If memory serves, the essence of the rejected report was published as a scholarly article (without reference to the Commission) and an English translation was published in one of Zagano's book of essay by multiple authors. I've looked but can't find it just now, and can't recall the author's name. Probably lent out, never to return....  Sorry. 

Frankly, Trid, I have no personal information on this. I'm merely reporting what I heard at this conference last summer.
