So let me get this straight.  You want to remove the empty tags, right?

You could say something like this

<xsl:template match="ListofDescription">
  <xsl:if test="child::DescInfo">
    <ListOfDescription>
      <xsl:apply-templates/>
    </listOfDescription>
  </xsl:if>
</xsl:template>

The test sees whether the <ListofDescription/> happens to have one of the
two valid children.  Or else it does nothing at all.
