sax spec requires local name

I posted this as a mail note a while back:

The problem came about when I tried using the save method in cocoon with saxon. With xalan everthing works fine, but not with saxon. Michael Kay claims that saxon is correct:

according to the sax spec:

So, no big deal but it definitely breaks unless the patch I will attach is applied.
