Producing CDATA sections with XML transformers

I'm trying to produce CDATA sections from the code in XML transformers. I'm unable to this with the following code (only plain text is outputed):

object AddCDATATransformer extends RewriteRule {
  override def transform(n: Node): Seq[Node] = n match {
    case n: Text => scala.xml.PCData(n.text)
    case _ => n

Strangely enough this succeeds :

n.copy(child = scala.xml.PCData(v) ++ n.child.tail)

Can someone explain this? How to get consistent results?

PS. I googled out that there is some -Xxml:coalescing flag but cannot find any documentation on how to use it.
