I would prefer that they could be called.

I actually see a very big difference for the user running Ant.  A
target-group has an higher granularity.  A normal user would rather
use that granularity level.  Only "advanced" users (probably the
developpers who wrote the script) could still call lower level part.

I would say that target-group, target-part are different level of
abstraction.  What part constitues the group are implementation
details that should be +/- hidden for the normal user (and probably
for developpers of other part of the global script).


Maybe an other way to see the difference is to foccus on the
relationship PartOf, instead of foccussing on the distinction
target-group, target-part.
I think it is easier to see a difference beween PartOf and Depends relationship.


I'm not sure I clarified something...  I hope I didn't add more confusion ;-)
