While I will not have the time to sit down and give sufficient time to the entire document until the weekend, it seems that this was found to be the practice at one place. Every parish keeps record books and Sacramental registers today.
Yesterday the documents of Trent are exactly where I was searching for such a requirement (to keep a log and check people in as they came to mass but only after they paid a fee) and a brief search did not turn up anything.
My gut says that this is speculation instead of something required of the Church, I will do more reading!
