You are applying templates to "/", the root node. You don't have a template
that matches "/" in the relevant mode, so the built-in template gets
invoked. The built in template does apply-templates on its children (in the
same mode), so at this stage your template

<xsl:template match="FileService" mode="ReaperMode">

gets invoked. But (in XSLT 1.0) the built-in template doesn't pass its
parameters on.

Change apply-templates select="/" to select="/FileService" and all should be
well.
