Copying all child nodes...

Given some xml :

<note>
    <note_text>
       ...lots of stuff...
    </note_text>
</note>

where my template has matched on note, I would like to do copy-of on
the *children* of note_text , i.e. *excluding* note_text itself. I am
having an "end of day" braindeath experience. Can somebody bring me
insight?

thanks,

Ben
