Given the little I know about schema, it seems it requires to use a
type="BaseType" attribute when one want to use a derived type instead of the
type itself. The same technique could be used to disambiguate which is what,
not based on the type, but the element name instead.

Just thinking out loud, while reading the views of the Ant experts. --DD

<javac ...>
  <mypath type="src" .../>
  <mypath type="classpath" .../>
</javac>

With the patch I submitted, neither!  

In the above case, you would have to have
addSrc(Src) and addClasspath(Classpath) assuming both 
Src and Classpath both extend from Path.  Of course,
the element that is being added may be a derivative
of Src or Classpath also.

This, I think is a reasonable constraint if you plan
to be doing different things (obviously) in addSrc and
addClasspath.  If you do not plan to have differeing code
in these two methods, then all you need is addPath(Path)
