I have tried both :
       <xsl:copy-of select="." />
and

You are not copying the child nodes of VisualObject because you are not
using apply-tenmplates or copy-of  (in the (when) case), add
<xsl:apply-templates/> inside your xsl:copy at the point you want child
nodes processed (typically either before or after your generated nodes)
