 # Constrained containers
 
 In CSS, it is possible to have containers where all its resources conform to a given [SHACL](https://www.w3.org/TR/shacl/) shape.
-Providing shape validation ensures that applications can then rely on the fact that

+Only resources can be created that conform to the constraints of a constrained container.
 However, some additional restrictions are enforced by the server on that container:
 
 * It is not possible to add any non-RDF resources.
 * Creating containers within this constrained container is not allowed.
-* Requests that results into a resource where no targetClasses from the shape are present are prohibited and will thus produce an error.
