Maybe I'll write a simple parser for Validator 1.1 so you could say: <var> <var-name>test</var-name> <var-value>((prospect == null) && (prospectNameOrId != null) && (action != "Add Prospect"))</var-value> </var> Of course, since requiredif is just a rule in the sample apps, anyone else could write it too.
