If this is the case then should or shouldn't set/getAttribute() in DOM2
"intelligently" assume empty namespace ('')?  Also, is there any specification
on construction of DOM for XML documents?  Or does the DOM specs available at
W3C describe the construction process?  If so, can somebody tell me in which
section?

I guess it works fine on with 0.10.2b.
