* Used by {@link Consent} (specifically the main implementations {@link Allow} and {@link Veto}), with the
* idea being that the only things that can create {@link Consent} objects are {@link Facet}s.
*
*
* TODO: note, this is a work-in-progress, because the DnD viewer in particular creates its own {@link Allow}s
* and {@link Veto}s. The constructors that it uses have been deprecated to flag that the DnD logic should
* move into {@link Facet}s that implement this interface.
