Sam fixed a sudden issue detected when testing fedora collections on puka, where sectioned demo documents would not expand in my fedora collection. He is now using JQuery in his javascript, which requires colons (and periods) to be escaped. This is necessary since there are colons in fedora collection documents' PIDs.
