Note: Associate actions require that an occurrence of the target entity type already exists. Therefore, the identifier is included in the READ statement before the ASSOCIATE statement. However, DISASSOCIATE and TRANSFER actions require that an occurrence of the subject entity type is already associated. The READ statements for these actions are qualified using related to subject entity type instead of using identifiers. For DISASSOCIATE statements, a READ EACH statement is built if the relationship is any any-any many.

TRANSFER actions are only allowed whenever the property of the relationship between the subject entity type and the related entity type has been defined as transferable.
