Status: VERIFIED DUPLICATE of bug 301260

(Core :: DOM: Core & HTML, defect)

calling createElementNS(null, 'foo') should create a "foo" element in no namespace. If added to an element with a defined namespace and serialized, the element should have an xmlns="" attribute to express that it is in no namespace.

Reproducible: Always

I think this is actually a bug in the XMLSerializer, and not in the core DOM code.  The alert demonstrates that el does have a null namespace and null prefix (which is somewhat okay for DOM use).  I also think you're right in that the serialized version should have something different.  I won't confirm it yet, though, because I'm not 100% sure.

Also reference bug 312019, which deals with a lookupNamespaceURI / lookupPrefix bug.  It might be related somewhat (I don't know how the serializer does its work).
