Hi,

Backwards from Andrew's answer:

<xsl:stylesheet ...>

<xsl:variable name="repeater" select="/input/repeat"/>

<xsl:template match="repeat"/>
<!-- suppresses output on default traversal -->

<xsl:template match="data">
  <xsl:for-each select="item">
    <xsl:apply-templates select="$repeater" mode="repeat">
      <xsl:with-param name="item" select="."/>
      <xsl:with-param name="pos" select="position()"/>
    </xsl:apply-templates>
  </xsl:for-each>
</xsl:template>

<xsl:template match="repeat" mode="repeat">
  <xsl:param name="item" select="/.."/>
  <xsl:param name="pos" select="0"/>
  <item>
    <xsl:apply-templates>
      <xsl:with-param name="item" select="$item"/>
      <xsl:with-param name="pos" select="position()"/>
    </xsl:apply-templates/>
  </item>
</xsl:template>

<xsl:template match="value-of">
  <xsl:param name="item"/>
  <xsl:value-of select="$item"/>
</xsl:template>

<xsl:template match="position-of">
  <xsl:param name="pos"/>
  <xsl:value-of select="$pos"/>
</xsl:template>

</xsl:stylesheet>

Untested.

Cheers,
