They have to be separated by "\n" as follows.

(defun echo-region-prefix (beg end arg)
  "Echo the region and prefix parameters."
  (interactive "r\nP")
  (message "region: (%s %s); prefix: %s" beg end arg))

I tested it in GNU Emacs 23.0.60.1 (i686-pc-linux-gnu, GTK+ Version
2.12.0) of 2008-12-15.
