 # Distinct object types
-For more explicit control over object type relations you can use `distinct` object types. Each distinct object type declaration has a unique type ID. When you include a distinct object type within another object type declaration, the new type's type ID set will include the type ID of the included type. When checking if a given object type `OSub` is a subtype of a distinct object type `OSuper` there is the additional requirement that `OSub` must contain all the type IDs of `OSuper`.
 
-This way you can achieve the same behavior as a nominal type system within the Ballerina's structured type system, which is useful for things such as GraphQL API interfaces.
