55 * This class is a context album container and holds a map of the context albums for an entire Apex model. All Apex
56 * models that use context albums must have an {@link AxContextAlbums} field. The {@link AxContextAlbums} class
57 * implements the helper methods of the {@link AxConceptGetter} interface to allow {@link AxContextAlbum} instances to
58 * be retrieved by calling methods directly on this class without referencing the contained map.
60 * <p>Validation checks that the container key is not null. An observation is issued if no context albums are defined in
61 * the container. If context albums do exist, they are checked to ensure that keys and values are not null and that the
62 * map key matches the key in the map value for all album entries. Each context album entry is then validated
