An SP may request multiple EntityConcernedTypes in an identifier set. The SP may also indicate to honor restrictions. When an Attribute with a ServiceRestriction is included in the AttributeStatement, users can access the service under the restrictions as specified for that type of restriction. Currently, the only restrictions supported are ServiceRestriction:Vestigingsnr and ServiceRestriction:SubdossierNr (deprecated). The ServiceRestriction:Vestigingsnr CAN be indicated in the Service catalog, in such case both the ServiceRestriction:Vestigingsnr and ServiceRestriction:SubdossierNr will be returned, if applicable.
