You can't. Well for a variable you can as you just need to look at the
text of the stylesheet, it never depends on run time behaviour, but for
a parameter it is not possible to tell without using an extension

<xsl:variable name="treeTest">
    <xsl:copy-of select="$cmdRequest"/>
  <xsl:when test="$treeTest/node/node()">

                           ^ that is a syntax error, you can not (in
                           XSLT 1) apply / to result tree fragment
