/**
 * Validates values against constraints defined in {@link MetadataInterface}
 * instances.
 *
 * This interface is an implementation of the Visitor design pattern. A value
 * is validated by first passing it to the {@link validate} method. That method
 * will determine the matching {@link MetadataInterface} for validating the
 * value. It then calls the {@link MetadataInterface::accept} method of that
 * metadata. <tt>accept()</tt> does two things:
 *
 * <ol>
 * <li>It calls {@link visit} to validate the value against the constraints of
 * the metadata.</li>
 * <li>It calls <tt>accept()</tt> on all nested metadata instances with the
 * corresponding values extracted from the current value. For example, if the
 * current metadata represents a class and the current value is an object of
 * that class, the metadata contains nested instances for each property of that
 * class. It forwards the call to these nested metadata with the values of the
 * corresponding properties in the original object.</li>
 * </ol>
