That query slipped my hands - I meant to write a URI fragment. Thanks for pointing it out, Philip. Other examples are spatial fragments: <video src="video.ogv#xywh=10,10,40,40"> or track fragments: <video src="video.ogv#track=audio&track=video"> or named fragments: <video src="video.ogv#id=couple_in_focus"> but the temporal fragments are the most important ones. Cheers, Silvia.
