	<!-- put this in an existing template -->
	<xsl:call-template name="loop">
    <xsl:with-param name="start-val" select="'1'"/>
    <xsl:with-param name="end-val" select="'10'"/>
  </xsl:call-template>


<!-- loops from $start-val to $end-val with a step value of 
	$increment 
-->
<xsl:template name="loop">
  <xsl:param name="start-val" select="'0'"/>
  <xsl:param name="end-val" select="'0'"/>
  <xsl:param name="increment" select="'1'"/>


  <xsl:if test="$start-val &lt;= $end-val">

		<!-- do stuff here, i just print out the number -->
		VALUE:    <xsl:value-of select="$start-val"/>

    <!-- recurse -->
    <xsl:call-template name="loop">
      <xsl:with-param name="start-val" select="$start-val + $increment"/>
      <xsl:with-param name="increment" select="$increment"/>
      <xsl:with-param name="end-val" select="$end-val"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>
</xsl:stylesheet>


I know this is much more work than for( int x=1; x <= 10; ++x ), but 
I think it is the only way to do it in XSL.  I'd appreciate anyone's 
suggestions or alternatives.

(As always this is briefly tested and worked for me ( Xalan1.2), your 
results may vary)
