I don't want to use ADFArgument because with ADFArugment only terminals are
accapted as argument. It's in the code of ADFArgument itself!
What I want is an ADF that takes as argument a subtree! I know the type of
the root of that tree (it's the If function which takes 3 arguments). So
basically I want to be able to have the following trees.

This is the result producing branch:

          if
           |
-----------------------------
|           |               |
xx         ADF              xy
            |
           if
            |
        ----------
        |    |    |
       yx    yy   yz

I hope the lay out won't be messed up.
