I think Grendel raises a good question, and your post does not address it.
You usually have to open the cause for canonization first so people know whom to report any potential miracles to.
An inquiry has been initiated to determine if Father Capodanno merits canonization by the Church. The details of that inquiry, which has just begun, apparently weren't included in the homily. The process of the inquiry is an extremely lengthy and detailed one. If the two of you are curious stay tuned. There will be more information forthcoming at a later date as the inquiry proceeds.
