Major Description
This is a modification to the enhancement introduced with CF-3692.
The append-post-include mode previous inserted the specified new element as the first child element. This option did not add any value as the same result could be attained using the append-pre-include usage on the first child (i.e., inserting the specified new element in front of the first child).
Therefor, this patch changes the behavior of append-post-include to insert the specified new element as the last child element. This operation was previously not possible.
