/**
* The name of the attribute which was changed, or null.
*/
readonly attribute DOMString attrName;
There should be probably also attribute namespace
void batchAttrChanges(in Node aNode);
A filter could be added here
-void batchAttrChanges(in Node aNode);
+void batchAttrChanges(in Node aNode, [optional] in DOMString
aReportValues);
Where aReportValues could a comma separated list of attr localNames, or
*. Default would be to report only that the attribute has changed, but
to not include any values.
