What's the s9apiest way to say text { $i } ?

Hi, I'm trying to express this bit of XQuery directly in s9api:


typeswitch ( $i )
  case $a as attribute(*) return text { $a }
  default return $i



I think it would be something like this (i an XdmItem),
but what's the s9apiest way to write the ??? below?



if ( i instanceof XdmNode n ) {
  if ( ATTRIBUTE != n.getNodeKind() )
    return n;
  return ??? /* make a text node from n.getTypedValue() */
}
else
  return i;


Thanks!
