Let me ask first: have you read the entire thread, or just the last post ?
Namespace are necessary for elements, there is no doubpt about it. But an
attribute only has meaning embedded in an element. Namespaces allows you to
uniquely identify elements. From elements you can reach the attributes. You
cannot access the attributes without their enclosing element anyway.
Let me put the problem from another perspective: is it useful to have
element A in namespace AAA and its attribute B in namespace BBB ?
