DOM 3 Core states [1]:

   "In programming languages where empty strings can be differentiated
    from null, empty strings, when given as a namespace URI, are
    converted to null"

So, if I understand correctly, createElementNS("", "p") is effectively 
the same as createElementNS(null, "p").

Interestingly, though, Opera has the opposite bug.  We fail when null is 
passed instead of "".
