Hi Dominic,
The behaviour of $node-> toString is (IMHO) still correct. You have 
just unbound the node from the DOM tree but it still belongs to the 
tree and NS declarations will be added (if necessary) as soon as 
you try to attach it again. 

But this: create a new document and place your $barbar node into it:

$doc2 = XML::LibXML::Document-> new;
$doc2-> adoptNode($barbar); # not necessary, setDocElement does it 
anyway
$doc2-> setDocumentElement($barbar);
print $doc2-> toString;

Works for me.
