Placeholders allow the receiving side to mirror the sender's ZFS dataset hierarchy without replicating every filesystem at every intermediary dataset path component.
Consider the following example: ``S/H/J`` shall be replicated to ``R/sink/job/S/H/J``, but neither ``S/H`` nor ``S`` shall be replicated.
ZFS requires the existence of ``R/sink/job/S`` and ``R/sink/job/S/H`` in order to receive into ``R/sink/job/S/H/J``.

In case of conflict, the algorithm errors out with a conflict description that can be used to manually or automatically resolve the conflict.

The algorithm ensures that a plan can be executed exactly as planned by aquiring appropriate zfs holds.
