I recently started using Warehouse App Task Validation. The variable replacement feature using @varName syntax in the edited XML gives us a way to deal with control names that are repeated over the course of the full task recording. This is certainly a nice feature and allows us to deterministically associate differing data which each control occurrence having the same name. However, I believe from a design perspective it would be better to define variables on a per recorded step basis rather than per full task recording. I don't think a given control name is ever reused on a per step basis so if we could define variables per step we could deterministically assign data to reoccurring control names without using the manual edits and @varName syntax.
