"http://meta.crazydreams.org/", hereafter "meta", is a namespace containing any and all names of the form "http://meta.crazydreams.org/foo" where "foo" is itself some namespace name. The meta namespace contains nothing else. The meta namespace defines each name that it contains to be a namespace name identifying a namespace identical to the namespace identified by the name following the "http://meta.crazydreams.org/" portion. For example, if "foo" were a real namespace, then the meta namespace would contain the name "http://meta.crazydreams.org/foo" and there would exist a namespace "http://meta.crazydreams.org/foo" that would be identical to the namespace "foo".
