In fact, you're right, this would be much better. Rather than change the 
parent of the original, just create a temporary copy that gets attached as a 
child of the fo:retrieve-marker. Because the original should stay where it 
is for future marker operations. In any case the code does not permit the 
original to be laid-out, so there is no problem leaving the fo:marker there.
