How do I use DTD's with Scala 2.3.0's XML object l: msg#00491 lang.scala

Hi,

I'm using scala's wickedly cool XML object literals (great idea - no more need
for Freemarker or Velocity for XML - could we have them for other things, too,
please... like a compile time templating engine!) to generate XHTML reports for
rehersal. To create valid XHTML, I need to have a DTD before the first element.
However, the compiler complains if I have a method like this:-

private def template(category: TestCategory) =
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>

<head>
<meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8"/>
<title>{category.name} Testing Results</title>
<style type="text/css" media="all">
(SNIPPED lots of content)

Removing the DTD causes it to compile.

Does anybody know why?

Additionally, does the compiler or API understand XML and HTML literals? Is ther
a utility method I could use to convert strings?

Many thanks

Raph

For information, the compile error (I'm using scalac in ant, with Scala 2.3.0)
is:-
