Extension-element-prefixes

[Gabriele Cressman-Hirl]

Hi,

I asked this question a while back, and did not see any responses.  Can
someone please point me in the right direction?

The problem:

        I'm using "redirect" to create a new xml instance document.
That works fine.  But I want to make the new document XML schema
compliant.  In order to do that I need to insert
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";  as a namespace
declaration into to root element.  

        This is the simplified code snippet:

                <redirect:write
select="concat($outputDirectory,'/',/product/domainProductName,'_Difficu
ltyDefinition.xml')">
                        <difficultyDefinition>
                                <xsl:copy-of select="@*"/>
                                <xsl:apply-templates />
                        </difficultyDefinition>
                </redirect:write>               

        I thought I should be able to use
xsl:extension-element-prefixes="xsi" at the element 

                <difficultyDefinition
xsl:extension-element-prefixes="xsi">

        having xsi defined as the namespace at the beginning of the
xslt.

        But that has no effect, as well as <difficultyDefinition
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";  >

        Does "xsl:extension-element-prefixes" not work with "redirect"?

        What am I missing?  Thanks for your help
