Getters and setter methods on Element classes that return strings can be optimized into a single function call that just takes the V8 parameters and the QualifiedName of the attribute (and the new value, for the setter.)
I've also thrown in a small optimization to the event handling that avoids multiple calls to V8Proxy::setDOMException in a single method.
