This determines the object to inject when the service stills unavailable when the timeout expires.Several values are supported:- 'nullable' means that a Nullable object will be injected- 'empty-array' injects an empty array (only for aggregate dependency)- 'null' injects Null- any other value are interpreted as the default implementation class to use.If the onTimetout attribute is not specified, a RuntimeException is thrown when the timeout is reached.</xs:documentation>
