Does taking levels in a prestige class cause XP Penalty?

Question

In D&D 3.5, does taking levels in a prestige class cause the XP penalty like multiclassing does? Please provide the source of the answer so I can show it to my players.

Answer 1

According to the srd, no, taking a prestige class does not cause an XP penalty. To grab the quote:

Taking a prestige class does not incur the experience point penalties normally associated with multiclassing.
