Now I am wondering what oldNs is even used for here, it seems from the libxml code it is really only needed to "cache" a pointer to the xmlNs that represents "xml" and nothing more.
No, the oldNs list is also appended to in `xmlDOMWrapStoreNs`. It seems that this namespace list is only used for memory management. From a quick look, your changes to the PHP code will cause a memory leak.
