55 * This class is a context schema container and holds a map of the context schemas for an entire Apex model. All Apex
56 * models that use context schemas must have an {@link AxContextSchemas} field. The {@link AxContextSchemas} class
57 * implements the helper methods of the {@link AxConceptGetter} interface to allow {@link AxContextSchema} 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 error is issued if no context schemas are defined in the
61 * container. Each context schema entry is checked to ensure that its key and value are not null and that the key
62 * matches the key in the map value. Each context schema entry is then validated individually.
