Hi.

Sorry for my late response, I was on holiday.

I installed the new versions (libxml2-2.6.4 and libxslt-1.1.2) and the
problems with nested entities I mentioned in my first email did not
occur anymore.
However, xsltproc still ignores the cdata-section-elements attribute:

> xsltproc testcase7.xsl testcase.xml
<?xml version="1.0" encoding="iso-8859-1" standalone="yes"?>
<script xmlns="http://www.w3.org/2000/svg"; type="text/ecmascript">
  var foo2 = text;
  </script>


> xsltproc --version
xsltproc was compiled against libxml 20604, libxslt 10102 and libexslt
802
libxslt 10102 was compiled against libxml 20604
libexslt 802 was compiled against libxml 20604

(See attachments testcase7.xsl and testcase.xml)

Regards,

Markus
