+    The "setData(data)" method for a processing instruction causes the 
+   DOMException NO_MODIFICATION_ALLOWED_ERR to be raised
+   if the node is readonly.
+   
+   Create an ent4 entity reference and add to document of the THIRD "gender" element.  The elements
+   content is an entity reference.  Try to remove the "domestic" attribute
+   from the entity reference by executing the "setData(data)" method.
+   This causes a NO_MODIFICATION_ALLOWED_ERR DOMException to be thrown.
