Simply because you *have* to pass a parent to the function...

There isn't a way -- and there are good reasons. One is memory management  
(it would create reference cycles, and they aren't efficiently removed).  
Another one is that it prevents an element to be shared between containers.

Then pass the desired parent as the "parent" argument.

Just because Element and SubElement are documented as the recommended way  
to create Element instances. Also, I was under the impression that  
makeelement did not make a copy of its "attrib" argument, so it would end  
being shared by other instances too -- but it isn't the case actually.
