<hr><a name="_details"></a><h2>Detailed Description</h2>
When associating an object to a key on a node using <code>setUserData</code> the application can provide a handler that gets called when the node the object is associated to is being cloned or imported.
<p>
This can be used by the application to implement various behaviors regarding the data it associates to the DOM nodes. This interface defines that handler.<p>
