      <elt greeting="Hello world!" />
    </root>

    <Layout xmlns="urn:speedata.de:2009/publisher/en"
      xmlns:sd="urn:speedata:2009/publisher/functions/en">

      <Options mainlanguage="English (USA)"/>

      <Record element="root">
        <ProcessNode select="elt"/>
      </Record>

      <Record element="elt">
        <PlaceObject>
