Take a look at the "Developing with Ant section" in the manual.  If
your nested <file> element is supposed to be implemented by a class
Ernie, you need to implement one of the three following methods in
your task:

(1) public Ernie createFile()

(2) public void addFile(Ernie anErnie)

(3) public void addConfiguredFile(Ernie anErnie)

(1) places the burden of creating the Ernie instance on the task,
while (2) will pass a new instance from the outside (this means that
Ernie needs a public no-arg constructor for Ant to work).  (3) is
similar to (2) but the setXYZ methods of the Ernie instance have been
called with values taken from the attributes before it gets passed to
your task.
