Hi Frank,
I have a solution in mind for you, the only thing is that using your input data above, the target schema will not show the elements outputfield3 and outputfield4 (but still have Description 3 and Description 4 in the data).
I have the schemas, map and XML files (for testing) in a zipped file but can’t post it here in the forums. If you are interested in it, go to my profile and you can download that zipped file from there and incorporate those artifacts in your own project…
Daniel.
