025/**
026 * Container annotation that aggregates several {@link PropertySource} annotations.
027 *
028 * <p>Can be used natively, declaring several nested {@link PropertySource} annotations.
029 * Can also be used in conjunction with Java 8's support for <em>repeatable annotations</em>,
030 * where {@link PropertySource} can simply be declared several times on the same
031 * {@linkplain ElementType#TYPE type}, implicitly generating this container annotation.
