[xslt] xsl:value-of a CDATA section is empty

["Stephan Otte" <Stephan Otte pcc de>]

Hello,
In my xml input file there is a CDATA section:
....
<data>
<next><![CDATA[from=20.05.2001&to=21.05.2001&name=donald]]</next>
</data>
...

I want to output the content of this section with the following xsl fragment:
...
<xsl:output method="html"/>
...
<a href="/cgi-bin/data.pl?{/data/next}">next page</a>
....

But in the output of xsltproc nothing is inserted from the CDATA section.
Same result with use of "<xsl:value-of ..>".
The example works with xalan xslt-processor, so what is wrong?

Any help?

Stephan
