I just made the following commit to libxml2 to fix the handling of ID 
attributes in xmlSetTreeDoc:

https://git.gnome.org/browse/libxml2/commit/?id=f54d6a929af2a570396f0595a0e29064c908c12e

Now, you can also remove a node with:

    XML::LibXML::Document->new->adoptNode($node);

By moving the node to separate document, its original attributes are still 
available and the redefinition warning is prevented. This is somewhat 
expensive, especially if you choose to create a new document for every node 
removed this way. The latter might be required to avoid id clashes in the 
"adopter" document.
