Won't be a problem. We'll just need to use the appropriate <condition>s to 
set a variable correctly.

Actually, I think that having the <if> check for "false" is cool, but the 
condition that it uses to do this shouldn't be called "IsSetCondition". This 
is a bit misleading. Maybe we should rename that to "IfCondition" or 
"TestCondition", and add an IsSetCondition which does just that, checks if a 
property is set. (I'll add this as part of my next round of changes, because 
I'll need a true IsSetCondition to provide proper Ant1 compatibility).
