How to write the tag using scala.xml and Play Framework

Can anyone tell me how to write the "xml" tag to the output? As expected, loadString() method gets rid of it while loading.

object SitemapController extends Controller {

  def validDeals = Action { implicit request =>
    val xmlStr = "<?xml version="1.0" encoding="UTF-8"?><msg>There's no xml tag</msg>" 
    Ok( scala.xml.XML.loadString(xmlStr) )
  } 
}

What I get beck from the controller is just

<msg>There's no xml tag</msg>
