But a containment relationship does not imply an ISA relationship in
most ontologies. I don't want to make a new subtree with lion and animal
nodes. A lion in an animal would seem to me to mean "WAS EATEN BY" :).

Rather, I want to have a node which can be interpreted as either a lion
or an animal.
