Description

We don't have static instance of {{SyntaxChecker}}s. This is annoying, because we have to dynamically instanciate them when we need to validate a value. Adding something like :

public class BooleanSyntaxChecker extends SyntaxChecker
{
    /** A logger for this class */
    private static final Logger LOG = LoggerFactory.getLogger( BooleanSyntaxChecker.class );
    
    /**
     * A public instance of this SyntaxChecker
     */
    public static final BooleanSyntaxChecker INSTANCE = new BooleanSyntaxChecker();
...

would help.
