/**
 * TValidationSummary class
 *
 * TValidationSummary displays a summary of validation errors inline on a Web page,
 * in a message box, or both. By default, a validation summary will collect
 * {@link TBaseValidator::getErrorMessage ErrorMessage} of all failed validators
 * on the page. If {@link getValidationGroup ValidationGroup} is not
 * empty, only those validators who belong to the group will show their error messages
 * in the summary.
 *
 * The summary can be displayed as a list, as a bulleted list, or as a single
 * paragraph based on the {@link setDisplayMode DisplayMode} property.
 * The messages shown can be prefixed with {@link setHeaderText HeaderText}.
 *
 * The summary can be displayed on the Web page and in a message box by setting
 * the {@link setShowSummary ShowSummary} and {@link setShowMessageBox ShowMessageBox}
 * properties, respectively. Note, the latter is only effective when
 * {@link setEnableClientScript EnableClientScript} is true.
