Explanation
The Explanation UI element is used to display single-line or multi-line help texts for UI element or a Web Dynpro application. The help text is generally edited at design time by the relevant documentation developer or technical editor (but not by the software developer) in the Web Dynpro ABAP authoring environment.

To permit the development of accessible applications, the tooltip property is not checked during design time, since there is no real need for a tooltip with this UI element.
