  * You can programmatically control the text displayed in the control by setting
- * the <b>Text</b> property. If the <b>Text</b> property is empty, the content
- * enclosed within the TLiteral control will be displayed. This is very useful
- * for reserving a location on a page because you can add text and controls

- * Note, <b>Text</b> is not HTML encoded before it is displayed in the TLiteral component.
- * If the values for the component come from user input, be sure to validate the values
- * to help prevent security vulnerabilities.
