I'm not sure if you or others realize this since I just learned it
myself (:)) but

  <xsl:variable name="empty_string"/>

is equivalent to your expression (XSLT Spec 11.2).  However, I don't
think that this is working in XalanJ at the moment so your form is
definitely safer until I get in the patch for that bug.
