What is the boost::serialitzation helper file? Oh maybe its what i called a 
wrapper

How much time/effort did it take to do this?

Hmmm - location as ? point to the line/character? current name? or ?

make_...wrapper is not recurssive, save/load are.

I would derive from xml_?archive and override the save(NVP(T)..) and/or
load(NVP...) to capture/whatever the tags as they are read/writting.  Don't
forget to call the original save/load.
