https://bugs.webkit.org/show_bug.cgi?id=41519

           Summary: Unable to create xmlns attribute
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: XML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: laurens.nospam at grauw.nl


This incorrectly fails with a NAMESPACE_ERR:

  document.createAttribute('http://www.w3.org/2000/xmlns/', 'xmlns')

The problem is here: http://trac.webkit.org/browser/trunk/WebCore/dom/Document.cpp#L850

This code only checks for prefixes, whereas the spec says that this should also check for qualified name:

-    if ((qName.prefix() == xmlnsAtom && qName.namespaceURI() != XMLNSNames::xmlnsNamespaceURI) || (qName.prefix() != xmlnsAtom && qName.namespaceURI() == XMLNSNames::xmlnsNamespaceURI))
-        return true;
+    if (((qName.prefix() == xmlnsAtom || qName.toString() == xmlnsAtom) && qName.namespaceURI() != XMLNSNames::xmlnsNamespaceURI) || ((qName.prefix() != xmlnsAtom || qName.toString() == xmlnsAtom) && qName.namespaceURI() == XMLNSNames::xmlnsNamespaceURI))
+        return true;
