Description:
------------
When using $node->set_attribute on a previously existing attribute with a namespace, the attribute gets doubled rather then updated - interestingly enough, a second update does update the "doubled" attribute just fine...

Additionally, $node->remove_attribute('test:attrib'); doesn't work with the previously existing attribute either while it removes the newly doubled attribute.

Reproduce code:
---------------
$dom=domxml_open_mem('<?xml version="1.0" ?><foo:root xmlns:test="http://test.de/xml" xmlns:foo="http://test.de/foo" test:attrib="0" />');

 $root = $dom->document_element();  
 $root->set_attribute('test:attrib','1');
 $root->set_attribute('test:attrib','2');
 
 echo $dom->dump_mem();

Expected result:
----------------
<?xml version="1.0"?>
<foo:root xmlns:test="http://test.de/xml" xmlns:foo="http://test.de/foo" test:attrib="2"/>

Actual result:
--------------
<?xml version="1.0"?>
<foo:root xmlns:test="http://test.de/xml" xmlns:foo="http://test.de/foo" test:attrib="0" test:attrib="2"/>

Just found a "workaround" to avoid invalid xml:

  $root->remove_attribute('attrib');  

That will remove the "original" attribute. Yes, without the namespace-prefix!

Namespace Support is pretty week in PHP 4...

If your solution works for you, fine. But it's not the DOM way to do it. It would be ->set_attribute_ns($namespaceURL,$attributeName)
But that doesn't exits in domxml in php4

That's all fixed in php5 and dom.
