DataReferenceTargetDefinition

A typed data definition class for the entity reference target_id property.

The target_id property differs from other data definitions in that it is required at the storage level, but not at the validation level. This is because its value can be set just-in-time using the preSave() method.

Validation for the target_id property is provided by the 'ValidReference' validation constraint.
