As far as I know, prefixes can have different bindings at different levels in the hierarchy, manipulating the tree may result in invalid prefixes in DOM1 and DOM2. In DOM2 you have a chance to "repair" the prefixes while writing out the tree since I know the namespace URI.... The methods I was talking about were mainly attribute access methods. What I would expect is that they use the elment namespace as a default. In a plain DOM1 situation, the element has no namespace, and DOM1 behavior is preserved. But in the current specification this is not fixed. Thus, the DOM1 read methods will work in most cases, but will deliver unpredictable results when I have two attributes with the same local name but different namespaces. That seems very dangerous to me. Best regards Stefan xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
