[KCFusion] deletes on database?

[Adaryl Wakefield]

I once saw a job announcement that said something to the effect. "..no deletes on the database will be allowed. All deletes are done via XML..." At the time I just raised my eyebrow and went on but now I'm kinda curious if anybody can shed some light on what exactly they meant. I only have an academic understanding of XML and a small one at that. A.
