On clapping in Church, and whether one should (ever)

Fr. Z comments on an article in Catholic Exchange titled, "Hold the Applause: Confessions of a Conflicted Clapper", which begins with this arresting statement:

"Whenever applause breaks out in the liturgy because of some human achievement, it is a sure sign that the essence of the liturgy has totally disappeared and been replaced by a kind of religious entertainment."

Now guess who said that? Pope Benedict XVI.

Cardinal Arinze, head of Divine Worship and the Discipline of the Sacraments, is also quoted:

"…when we come to Mass we don’t come to clap. We don’t come to watch people, to admire people. We want to adore God, to thank Him, to ask Him pardon for our sins, and to ask Him for what we need.”

Now, my question: does proper liturgical praxis involve never clapping during Mass (ever)?
