Not if you construct the recursive template correctly.

Passing it a negative number as a parameter (let's say you have 55 orders: 
the parameter passed will be (50 - 55) = -5), you can easily "fall through" 
and choose not to emit output or recurse:

<xsl:template name="write-blanks">
  <xsl:param name="counter" select="0"/>
  <xsl:if test="$counter > 0">
     ... write your blank line here ...
    <xsl:call-template name="write-blanks">
      <xsl:with-param name="counter" select="$counter - 1"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>

Cheers,
Wendell
