& XSLT I have a problem with namespaces after removal of a node from a 
document.  I want to remove a node, then write it out to disk as a 
standalone fragment.  But the namespace declarations are going missing.

For example:

   my $doc = $p-> parse_string(
     '<foo xmlns:bar="http://example.com/"> <bar:bar /></foo>'
   );
   my $barbar = $doc-> firstChild->firstChild;
   $barbar-> unbindNode();
   print $barbar-> toString();

Outputs:

   <bar:bar/> 

Instead of:

   <bar:bar xmlns="http://example.com/"/> 

And I can't see why this is happening?  Can anyone help me with this? 
I've attached the above as a test.

Thanks,
-Dom
