Setup Master Templates

I just found this “Setup Master Templates” in Dynamics NAV 5.0. It looks interesting but I have no idea of what it actually is. Who can tell me? Thanks.

It was supposed to define mandatory fields during import of Excel / XML files. You can define template in data migration. I never worked for me, You can also create a template and for example in customer card fill information from template. From RIM guide you have a description of it’s supposed to do.
