The text already says that the referenced agent must appear within the document, and there are restricted locations where it can be. I propose either reverting the edit or adding text to explain what distinguishes a \"significant\" agent from any other kind.\n\n(raised by Nigel Megitt on 2013-08-09)\nFrom tracker issue http://www.w3.org/AudioVideo/TT/tracker/issues/268"}}
