Log Message:
Changed Element parentage so only one variable is used for the parent.
It may be of type Element or Document depending on where the elt is placed
in the tree.  This saves one instance variable's worth of memory for each
element in the tree.  

On JDK 1.2.2 Windows it doesn't appear to change things (because of
passing in the memory layout I presume) but on JDK 1.3 Windows with 
HotSpot this definitely saves memory.  Performance appears no different
and in fact a little faster on the test cases.
