Watch out ... on this example:

<Q>
  <X>
    ... stuff ...
  </X>
  <Y>
    ... stuff ...
  </Y>
  <Z>
    ... stuff ...
  </Z>
</Q>

the above stylesheet would result in an empty document (nothing would be 
copied).

You could debug it by switching

<!-- ignore everything -->
<xsl:template match="*" />

to

<!-- by default, pass everything without copying
     (though since this template is built in it doesn't
      have to be included literally) -->
<xsl:template match="*">
  <xsl:apply-templates/>
</xsl:template>

<!-- by default, suppress text nodes
     (wanted text nodes are picked up in 'copy' mode -->
<xsl:template match="text()"/>

and also tweak

<xsl:template match="X|Y|Z">
  <xsl:copy>
    <xsl:apply-templates mode="copy" select="*|*@" />
  <xsl:copy>
</xsl:template>

to say <xsl:apply-templates mode="copy" select="node()|@*"/> -- since by 
selecting "*|@*" you'll skip the text nodes. (Or just say plain 
xsl:apply-templates mode="copy" and add an <xsl:copy-of select="@*"/> ahead 
of it to grab the attributes.

Cheers,
Wendell
