I bet it is. I used to do the same. Basically all the HTML*Element interfaces were implemented on the same class. But I finally decided that it was a bug in my implementation to make instanceof unreliable. Think about it. If instanceof(Attr) returns true, it'd better be an Attr node, or your users will get very confused. -- Arnaud
