/**
 * A type implemented by, or extended by maven itself.
 * Maven provides implementations of those types and may inject them in plugins.
 * <p>
 * A type can be marked {@link Consumer} or {@link Provider} but not both. A type is assumed to be
 * {@link Consumer} if it is not marked either {@link Consumer} or {@link Provider}.
 * <p>
 * A package can be marked {@link Provider}. In this case, all types in the package are considered
