Can SimpleXML still return all namespaces?

I was interested in this article http://www.onlamp.com/pub/a/php/2004/01/15/simplexml.html?page=2 and its description of the handling of namespaces in a beta version of SimpleXML where it simply ignores them, returning elements and attributes from all namespaces. Obviously this behaviour was changed by the time the final version was released, as now it only returns values in the default namespace (and doesn't seem to do that quite correctly; I have just filed a bug report http://bugs.php.net/42026). For me, the alternative behaviour would be useful/desirable. Is there a way to turn this on by a runtime option? As a second best, is there a value that can be passed to children()/attributes() that cause them to return names from all namespaces? If not, can I make a feature request of this? Where do I do so? I couldn't find anywhere on the website. I don't imagine it would be too difficult to implement as it's been there before! Ben.
