strictly taken, yes. It is also assumed that this will be a rather frequent 
situation, you have many cave systems where it is known that certain cave 
entrances or other objects belong to a cave system but not exactly how they 
are connected.
Even long after it is known to researchers there may not be anyone in the OSM
community abler or willing to map them in detail.

As the cave may have other cave-wide attributes there may be other reasons
to have a relation for it.
