How is this any better than just doing:
<property file="${customer}/settings.properties"/>
Or something like that???
I'm not sure I understand what you're getting at with deleting a property
and why you feel its needed?
So no, it doesn't clear things up! :)
Also, <antcall> gets its own set of properties, and does not affect the
calling set of properties, so what you've written wouldn't work even if you
could delete properties.
