You'd need something like "aItemClass: specialize
TMyGeneric<SpecificType>.TMyGenericClass", but that might not compile in
mode ObjFPC.
As an aside: if TMyGeneric would not be a generic you'd need
TMyGeneric.TMyGenericClass as well, a TMyGenericClass is part of
TMyGeneric's scope and TMyService does not know this scope.
