// The following requirement is tested:
// The default mechanism is evoked at the end of each alt statement, if due to the 
// actual snapshot none of the specified alternatives could be executed. An evoked 
// default mechanism invokes the first altstep in the list of defaults, i.e. the last
// activated default, and waits for the result of its termination. The termination can 
// be successful or unsuccessful.
