    This method validates the given value.
    
    Parameters:
    
    value - is the value to validate.
    
    valueSource - is the source describing the origin of the given value. The source needs to have a reasonable string-representation as this may be displayed to the end-user to locate the source of the failure. In most cases it is suitable to directly pass a String.
    
    Returns:
    
    the ValidationResult.
