 * Indicates that this class has a default.

 * The mechanism for providing a default will vary by the applib. In the Java applib, this is done by
 * implementing the DefaultProvider interface.
 * 
 * 

 * The rest of the framework does not used this directly, but instead we infer {@link PropertyDefaultFacet}
 * and {@link ActionDefaultsFacet} from the method's return type / parameter types, and copy over.
