docs: Traversal function for the "namespace" direction the
            namespace axis contains the namespace nodes of the context
            node; the order of nodes on this axis is
            implementation-defined; the axis will be empty unless the
            context node is an element  We keep the XML namespace node
             at the end of the list.
