Check that every reference in a child dataset resolves to a parent. Containment is one-directional, which is the difference from a reconciliation: a parent key nothing references is normal and is reported as a count, while a child key with no parent is a broken reference reported with every row carrying it. Also catches a duplicated parent key, which makes any reference to it ambiguous.
