Namespaces in XML are certainly a pain in the neck, few people nowadays dispute that. But I don't think you can equate them to the way namespaces are used in programming languages, because the naming architecture of XML is completely different (for example, there is no concept of information hiding). But I don't see where you are getting your analogies from. There is no restriction in Java, for example, that the type of a method must be related in any way to the name of the method. Method names and types in Java are completely orthogonal, and it seems entirely reasonable that element names and types in XML should also be orthogonal. Michael Kay
