[xsl] xsl:copy and disable-output-escaping

[Guenstig und Gut <guenstig-und-gut@xxxxxx>]

Hi,

I'm using Saxon-B 9.0.0.6. I've following XSL-Example:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="2.0">
   <xsl:template match="/">
       <xsl:variable name="test"><xsl:text 
disable-output-escaping="yes"><![CDATA[<b>5</b>]]></xsl:text></xsl:variable> 

       <xsl:copy-of select="$test"></xsl:copy-of>
   </xsl:template>
</xsl:stylesheet>

The output of $test in any browser is <b>5</b> but I want that the 
number 5 is bold. If I only use
<xsl:text disable-output-escaping="yes"><![CDATA[<b>5</b>]]></xsl:text>
it works. It also works using Xalan 2.70 processor. Can somebody help me?

That's only a example which shall explain my problem. I know that I 
could write <b>5</b> without <xsl:text> and without CDATA.

Thx Walter

ps: sorry for my bad english
