Well, short of implementing a full boolean expression language inside
Validator, it was the best I could do. 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.
