It's nice that you can create nodes with namespaces, using DomDocument->create_element_ns() and DomNode->add_namespaces(), but for actually reading them, there is no counterpart method (other than prefix(), which is not very safe).

My specific problem is that I want to clone a node without its child nodes, but can't use DomNode->clone_node(false), since this does not copy any namespace declarations and attributes either.

Adding a DomNode->get_namespace() in future versions would be greatly appreciated.
