XML data binding products often generate code for classes from an XML Schema or vice versa. If you can have unqualified (or even locally defined) children, then generating an XML Schema from a graph of class definitions is easy in that you don't have to worry about element name collisions. For example, suppose you have two classes: class foo class bar { { int x; String x; int y; String y; bar b; } } The existence of local element types means you can serialize objects from these classes as: <foo> <x>...</x> <y>...</y> <bar> <x>...</x> <y>...</y> </bar> </foo> The problem with local element types is that, once an element of the type is taken out of its containing element, it can't be identified. Allowing the child element names to be unqualified just exacerbates (sp?) the problem. What I can't understand about both is whether they solve any technical problems. As far as I can tell, the only problems they solve are aesthetic, since the objects could just as easily have been serialized as: <foo> <foo-x>...</foo-x> <foo-y>...</foo-y> <bar> <bar-x>...</bar-x> <bar-y>...</bar-y> </bar> </foo> -- Ron
