Aunque el sistema de inyección de dependencias jerárquico es muy simple de definir y usar, sigue siendo muy poderoso.

Puedes definir dependencias que a su vez pueden definir dependencias ellas mismas.

Al final, se construye un árbol jerárquico de dependencias, y el sistema de **Inyección de Dependencias** se encarga de resolver todas estas dependencias por ti (y sus sub-dependencias) y proporcionar (inyectar) los resultados en cada paso.

        Element root = doc.root();
        Element dependencies = root.child("dependencies").orElse(null);
        assertNotNull(dependencies, "dependencies should exist");
        Element dependency = dependencies.child("dependency").orElse(null);
        assertNotNull(dependency, "dependency should exist");

        // Insert elements in dependency according to dependency ordering
