/**
 * Describe the owning entity as being part of the target entity's
 * indexed object graph.
 * 
 * Often used when an {@code @Indexed} class is used as a {@code IndexedEmbedded}
 * target class. {@code @ContainedIn} must mark the property pointing back
 * to the {@code @IndexedEmbedded} owning Entity (not necessary if the class
 * is an {@code Embeddable} class).
 * 

 * Also used to trigger a reindex of related entities even if no
 * {@code @IndexedEmbedded} is involved, allowing to define a dependency
 * graph.
