<DL>
<DD>Simple tree walker that will clone recursively a node. This is to
 avoid using parser-specific API such as Sun's <tt>changeNodeOwner</tt>
 when we are dealing with DOM L1 implementations since <tt>cloneNode(boolean)</tt>
 will not change the owner document.
 <tt>changeNodeOwner</tt> is much faster and avoid the costly cloning process.
 <tt>importNode</tt> is in the DOM L2 interface.

<DD><DL>
<DT>Parameters:<DD><CODE>parent</CODE> - the node parent to which we should do the import to.<DD><CODE>child</CODE> - the node to clone recursively. Its clone will be
 appended to <tt>parent</tt>.
<DT>Returns:<DD>the cloned node that is appended to <tt>parent</tt></DL>
