There's an interesting aspect to that document:
87. When the election has canonically taken place, the junior Cardinal Deacon summons into the hall of election the Secretary of the College of Cardinals and the Master of Papal Liturgical Celebrations. The Cardinal Dean, or the Cardinal who is first in order and seniority, in the name of the whole College of electors, then asks the consent of the one elected in the following words: Do you accept your canonical election as Supreme Pontiff? And, as soon as he has received the consent, he asks him: By what name do you wish to be called? Then the Master of Papal Liturgical Celebrations, acting as notary and having as witnesses two Masters of Ceremonies, who are to be summoned at that moment, draws up a document certifying acceptance by the new Pope and the name taken by him.
88. After his acceptance, the person elected, if he has already received episcopal ordination, is immediately Bishop of the Church of Rome, true Pope and Head of the College of Bishops. He thus acquires and can exercise full and supreme power over the universal Church.
If the person elected is not already a Bishop, he shall immediately be ordained Bishop.
89. When the other formalities provided for in the Ordo Rituum Conclavis have been carried out, the Cardinal electors approach the newly-elected Pope in the prescribed manner, in order to make an act of homage and obedience. An act of thanksgiving to God is then made, after which the senior Cardinal Deacon announces to the waiting people that the election has taken place and proclaims the name of the new Pope, who immedi- ately thereafter imparts the Apostolic Blessing Urbi et Orbi from the balcony of the Vatican Basilica.
If the person elected is not already a Bishop, homage is paid to him and the announcement of his election is made only after he has been solemnly ordained Bishop.
What this apparently means is that any Catholic can theoretically become Pope.
If I were a liberal Catholic blogger, I'd advocate that a non-clergy person be elected Pope.
It's about time, after all.
