Problem: A leaf concept is a singleton, i.e. it has no siblings.
Solution: Add relevant sibling concepts to the singleton. Alternatively, if no such concepts exist or can be anticipated, then refactor EDAM to remove the singleton, e.g. repositioning it, or deprecating it / consolidating it wiht a parent concept.
Further information: None.
