>As to the edit paradigm.....doing drill-downs so that you are only editing from the parent-child standpoint (the parent begin relative) works, but I find *it* can be cumbersome. Look at the Office paradigm: If you edit an Excel worksheet and add macros, graphs, and new worksheets to the workbook and then exit without saving changes, all changes are gone.


Ummmm.... huh? If you Edit an Excel Workbook and add additional entities to the same workbook (graphs, macros, etc.) is that not an all inclusive edit tied to the superentity (originating workbook)?
