I have done a little further work on my patch
to allow nested elements to have Project type
as a constructor.

If the object contains both add<Element>() and create<Element>(),
the add<Element>() method is used.

example:
    <typedef myfileset mypath anttest etc ..>
    <copy todir="output">
      <fileset ant-type="myfileset" dir="src"
                  newattribute="MyFileSet attribute"/>
    </copy>

    <anttest>
      <path ant-type="mypath" path="build.xml"
                newattribute="MyPath attribute"/>
    </anttest>

I will upload the modified  patch over the weekend.
