namednodemapSetNamedItemWithNewValue
NIST
If the "setNamedItem(arg)" method does not replace an
existing node with the same name then it returns null.
Retrieve the third employee and create a NamedNodeMap
object from the attributes of the last child.
Once the list is created the "setNamedItem(arg)" method
is invoked with arg=newAttr, where newAttr is a
newly created Attr Node and whose node name
already exists in the map. The "setNamedItem(arg)"
method should add the new node and return null.
This test uses the "createAttribute(name)" method from
the document interface.
