Summary

Node.lookupNamespceURI() supports "xml" and "xmlns" prefixes by default. The function returns fixed namespace strings for them. Document.createNSResolver() and XPathEvaluator.createNSResolver() stops to wrap the specified node to add "xml" prefix handling. They return the specified node as is. Web developers can use an element as an XPathNSResolver without wrapping it with createNSResolver().
