Pb with identity transform in XT

I can't figure it out, the identity transform in XT appears to not
copy the document element.  Using the following stylesheet:

<stylesheet xmlns="http://www.w3.org/XSL/Transform/1.0">

<template match="@*|*|text()|processing-instruction()">
  <copy>
    <apply-templates select="@*|node()"/>
  </copy>
</template>

</stylesheet>

and the following document:

<hello bit="on">
  <world bit="off">How are you?</world>
</hello>

XT prints out:

<world bit="off">How are you?</world>

Where is my `hello' element?  What am I doing wrong?  This driving me
nuts, but I just can't see it.  Can anyone shed some light?

Thanks,
