Remarks

Resource-level change authorization and validation is implemented by methods annotated on the ChangeInterceptorAttribute. WCF Data Services provides the infrastructure required for service developers to write per-entity change processing rules and validation.

Entity-level access control and validation can be enforced through query interceptors. For more information, see QueryInterceptorAttribute.
