[xsl] dyn:evaluate question

[Thorsten Scherler <thorsten@xxxxxxxxxx>]

Hello list,

I am trying to dynamically include a stylesheet like this:
<xsl:variable name="request">index</xsl:variable>
<xsl:include href="cocoon:/prepare.include.dyn:evaluate($request)"/>

but the dyn:evaluate($request) -part will not get resolved.

As soon I change it to 
<xsl:include href="cocoon:/prepare.include.index"/>
I get my stylesheets.

Am I using the dyn:evaluate wrong? Are there a workaround?

TIA
