This issue is outside of my problem domain because:

1. You probably can't solve this for common objects like DTML methods 
because there's not enough meta-info in the body to determine how diffs 
should be applied.

2. For my project, synchronization of objects is always specified in one-
direction for a given folder or meta-type
