note 116855 added to domxpath.registernamespace

The documentation is not really detailed. Probably someone is also interested in the possibility of unregistering the namespace. Worths to note that the original libxml function "xmlXPathRegisterNs()" * Does NOT accept NULL or empty string for the argument "$prefix". and * Unregisters the namespace if the "$namespaceURI" argument is NULL.
