}

ValueDetector: '@' -> more, pushMode(ValueDecoder);

mode ValueDecoder;

EndOfValue : '@' -> popMode, type(DecodedValue);
SpecialChar
    : '&' ~([;])* ';'
        {
            final String text = getText();
            System.out.println("An & --> " + getText());
            setText("&" + getText().substring(1, getText().length() -1).toUpperCase() + ";");
        }
        -> more
    ;
Others : . { System.out.println("One more char: " + getText()); } -> more ;
