This approach, single namespace, would mean that a single schema would define both root elements, <mods> and <mads> (and whatever other root elements) and then could *include* (rather than *import*) xml for both mods and mads. I believe this would avoid the need for prefixes. And (as noted) it would also make processing easier. I do think however, from a "big picture" perspective, it would significantly inhibit flexibility. --Ray
