Filtering of a SINGLE property

Well, sure, we CULD do it at runtime, but
a) this would cost performance (okay, to be honest, of course, it could once
be loaded and runtime and so on, but still it would at least clutter the
code with additional stuff we didn't when we were using Maven 1).
b) For political reasons It would be good if everything would work as close
as possible as it was before I introduced Maven 2
