The processing should happen in order as the elements appear in
the file, but sorted by kind (e.g. first primitives, then groups,
then clones, then constraints). That's the only way to have
cibadmin cooperate because of possible dependencies. But the
order of elements should be otherwise preserved.

There's actually erase before load.
