3.1.1.2.5.1 Consistency and Safety Checks
This section documents schema object special behaviors that are not closely tied to the defunct state. These special behaviors are divided into two classes:
Consistency checks
Safety checks
Consistency checks maintain the consistency of the schema. Safety checks reduce the possibility of a schema update by one application breaking another application.
If an Add or Modify request fails either a consistency or a safety check, the response is error unwillingToPerform / <unrestricted>.
