Sorry for misunderstanding. Indeed, the control does not support such markup generation. If you like, you can log your feature request in our feedback portal: http://feedback.telerik.com/Project/108/. If it accumulates enough public interest, we will consider its implementation. If you also include the use case(s) you have and the way you expect it to work, it would greatly help set expectations and base line.
