What should the opposite be?
The mapping works both ways. It should take the old value from the 
property if it is there, otherwise from the XML content field. When 
saving your xml file, the value will be saved both into your xml field 
and into your property. In general, the mapping just works at edit time, 
it will change the way how existing files are interpreted when they are 
only being read.

If you want to somehow re-organize content and merge some properties 
into your XML content so that the data can then be read differently, 
then you might need to write a custom piece of code that does this kind 
of merging, since - as stated before - the mapping will only be 
evaluated, whenever the file is saved in the editor^.
