+ * This implementation of [EMAIL PROTECTED] IValidatable} is meant to be used
outside of
+ * wicket. It allows other parts of the application to utilize
+ * [EMAIL PROTECTED] IValidator}s to validate values.
+ *
+ * Example: <code>
+ * class WebService {
+ * public void addUser(String firstName, String lastName) {
+ * Validatable standin=new Validatable();
+ * standin.setValue(firstName);
+ * new FirstNameValidator().validate(standin);
+ * standing.setValue(lastName);
+ * new LastNameValidator().validate(standin);
+ * if (!standin.isValid()) {
+ * // roll your own ValidationException
+ * throw new ValidationException(standin.getErrors());
+ * } else {
+ * // add user here
+ * }
+ * }
+ * }
+ * </code>
