I couldn't find any evidence from the spec either. My understanding is that
Xerces doesn't import the event listeners when importing a node. So you
might have to re-register them again.

Your event listener would be called automatically. For example:
<root>
<child att="value"/>
</root>
// suppose node points to "root"
// initiate your listener
EventListener el = new MyEeventListener();
// register the listener
((EventTarget)node).addEventListener("DOMAttrModified", el, false);
// first child is a text node, the next is element "child"
Node child = node.getFirstChild().getNextSibling();
// get the attribute node
Node att = child.getAttributes().item(0);
// now change the attribute value, and el.handleEvent() is called
// at this point
att.setNodeValue("newValue");
