/**
 * allowed to use for classes which implement interfaces which have the marker @InvocationOrderSupport
 *
 * suggested ranges (mainly for name-mappers):
 * negative values for "extreme" cases
 *
 * 0-49 for custom artifacts which should have the highest priority
 * 50-99 for add-ons which provide artifacts which should have a higher priority than the default artifacts
 * 100-999 internal artifacts
 * 1000+ for custom artifacts
 *
 * suggested ranges for artifacts like interceptors,...
 * 1xx ... artifacts of the core
 * 2xx ... artifacts of validation modules
 * 3xx ... artifacts of component support modules
 *
 * a priority should be unique within one artifact-type - that means
 * if a name-mapper has priority 100, it's ok that an exception-interceptor also has priority 100.
 * but a 2nd name-mapper shouldn't have priority 100
