/** Annotation for associating a capacity and a default skill.
 *
 * <p>This annotation should be associated to a {@code Capacity}.
 * It takes a value that is the type of the skill that should be given to an
 * agent by default when it tries to use the capacity.
 * This annotation is similar to the {@code @ImplementedBy} annotation into
 * the injection library.
 *
 * <p>The SRE could use this annotation to create dynamically the skill when
 * the {@code Agent.getSkill()} is called.
 *
 * <p>This annotation is supported by an implementation of {@link DynamicSkillProvider}.
