  • As you are evidently aware, XML Schema adds data types to XML; this is evidently something that many people have found lacking in XML. Moreover, if you have typed data, then if you are using an untyped format, then at some point, you are mapping between typed and untyped forms, and vice versa, in which case you are essentially imposing your own type system.
