Java DOM implementations and cloneNode

It is not a well known fact that DOM Level 1 does not dictate inter-document
operations or movement of nodes between documents.  You will find that
following is true:

Node node1 = doc1.createElement("boo");
Node node2 = node1.cloneNode(false);
if (node1.getOwnerDocument() == node2.getOwnerDocument())
    System.out.println("both the original and the clone belongs to same
document");

So when you tried to populate the second document with clones of the first
document, you were trying to move nodes from one document to another.

I am quite sure that some DOM implementations allow you do this although it
means your DOM code will no longer work with all DOM implementations.  If
you are willing to stretch your neck just so, you might give the currently
available version 1.0PR3 at www.docuverse.dom/domsdk/ a try.  I am fairly
certain I added code for this.  If not, Docuverse 1.0 Beta 1 definitely will
(soon, real soon now).

Best,
