[xsl] Yet Another Entity Ref question!

[Marco Guazzone <sguazt@xxxxxxxxxxx>]

Hi,
I'd like to produce an entity reference, say "©", from XML to HTML
through XSLT; here below I have summarized the problem with an example:

XML
<?xml version="1.0"?>
<doc>
  <label>Foobar<entity>copy</entity></label>
</doc>

XSL:
<?xml version="1.0"?>
<xsl:stylesheet
    version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="html" media-type="text/html" encoding="ISO-8859-1"/>

<xsl:template match="doc">
   <xsl:apply-templates select="label" /> <!-- ok! -->
   <xsl:variable name="label">
      <xsl:apply-templates select="label" />
   </xsl:variable>
   <xsl:value-of select="$label" />  <!-- not ok -->
   <xsl:value-of disable-output-escaping="yes" select="$label" />  <!-- ok
-->
</xsl:template>

<xsl:template match="entity">
   <xsl:text
disable-output-escaping="yes"><![CDATA[&]]></xsl:text><xsl:value-of
select="." /><xsl:text>;</xsl:text>
</xsl:template>

</xsl:stylesheet>

So, if I use $label I have to disable escaping to get what I want.
I try to look for this problem on FAQ but I didn't find any interesting
solution.
Has anyone a better solution?
Thanks in advance!
