Wait... I thought I tried to use "*" with the default RulesBase rules, and 
got nothing.  I then discovered (and Craig simultaneously posted) that you 
have to tell your Digester to use the ExtendedBaseRules before the wildcard 
will work.  Are you saying that "*" is supposed to work without
    digester.setRules( new ExtendedBaseRules() );
?  Or... how can you do the same thing with RulesBase?  (I _do_ just want it 
to call setWhatever() for patterns for which there isn't any other match.)
