Recognises overlapping entities

What it means

Two entities whose meanings overlap, so the same thing can be recorded in both, and a change reaches only one.

How it is assessed

Flags the deficient case and passes the acceptable one. Deficient: Retail Customer and Account Holder Party as separate kernel entities with the same attributes Acceptable: One Party entity; customer and account holder as roles. Test: could one instance belong to both entities with the same key and meaning?
