[Mod_transform] I would like iso-8859-1, not utf8

[Stanislas Ormières]

Hello every body

I would like to output ISO-8859-1 with mod_transform, so I encode the .xml
and the .xml in iso-8859-1 and I Put these lines in the .xsl :

<?xml version="1.0" encoding="ISO-8859-15"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output
         method="xml"
         version = "1.0"
         encoding="ISO-8859-15"
         omit-xml-declaration="no"
         indent="yes"
         doctype-public="-//W3C//DTD XHTML 1.1//EN"
         doctype-system="http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"
         media-type="text/html"
         standalone="no"
         />

Can someone tell me what I do wrong, please ?

Thank you in advance, bye
