Cleaner than the method named after me would be to process the order nodes 
you have, and then pass the difference between 50 and their count to a 
recursive template that would emit the blank lines until zero (or less than 
zero) was reached:

<xsl:template match="orders">
  <xsl:apply-templates select="order"/>
  <xsl:call-template name="write-blanks">
    <xsl:with-param name="counter" select="50 - count(order)"/>
  </xsl:call-template>
</xsl:template>

(Since you've already seen the recursive template I leave it to you to 
adjust it -- and get the numbering of the blank lines right. ;-)

Cheers,
Wendell
