/**
 * Delegates to candidate {@code SmartContextLoaders} to process the supplied
 * {@link ContextConfigurationAttributes}.
 * <p>Delegation is based on explicit knowledge of the implementations of the
 * default loaders for {@linkplain #getXmlLoader() XML configuration files and
 * Groovy scripts} and {@linkplain #getAnnotationConfigLoader() annotated classes}.
 * Specifically, the delegation algorithm is as follows:
 * <ul>
 * <li>If the resource locations or annotated classes in the supplied
 * {@code ContextConfigurationAttributes} are not empty, the appropriate
 * candidate loader will be allowed to process the configuration <em>as is</em>,
 * without any checks for detection of defaults.</li>
 * <li>Otherwise, the XML-based loader will be allowed to process
 * the configuration in order to detect default resource locations. If
 * the XML-based loader detects default resource locations,
 * an {@code info} message will be logged.</li>
 * <li>Subsequently, the annotation-based loader will be allowed to
 * process the configuration in order to detect default configuration classes.
 * If the annotation-based loader detects default configuration
 * classes, an {@code info} message will be logged.</li>
 * </ul>
 * @param configAttributes the context configuration attributes to process
 * @throws IllegalArgumentException if the supplied configuration attributes are
 * {@code null}, or if the supplied configuration attributes include both
 * resource locations and annotated classes
 * @throws IllegalStateException if the XML-based loader detects default
 * configuration classes; if the annotation-based loader detects default
 * resource locations; if neither candidate loader detects defaults for the supplied
 * context configuration; or if both candidate loaders detect defaults for the
 * supplied context configuration
