Recognises a structural error in a taxonomy hierarchy

What it means

The hierarchy contains a cycle, a node that is not a concept in the model, or no declared root. Validator: `CON-008`, `CON-009`, `CON-010`, `CON-016`.

How it is assessed

Flags the deficient case and passes the acceptable one. Deficient: Current account → Payment account → Current account; `children: [CC-099]` where CC-099 does not exist Acceptable: Decide which is broader, or merge them if they are synonyms; add CC-099 to `concepts` before referencing it
