Ecclesia Dei: Answers of the Cardinal President of the Pontifical Commission "Ecclesia Dei" to certain questions

An interesting document has appeared on the Summorum Pontificum site of Ecclesia Dei today: Risposte del Cardinale Presidente della Pontificia Commissione “Ecclesia Dei” a certi quesiti (Answers of the Cardinal President of the Pontifical Commission "Ecclesia Dei" to certain questions).

An NLM translation has been in the works today and will hopefully be forthcoming soon. The gist of the piece is that it summarizes the earlier approach to the question of the usus antiquior in view of Quattuor Abhinc Annos (the original 1984 indult), the findings of the 1986 commission of Cardinals who studied the question of those liturgical books, and sets out to demonstrate the relation of these to the motu proprio, Summorum Pontificum.
