It's friday, so...

<xsl:template name="dateFormat">
  <xsl:param name="str" />
  <xsl:param name="date-format" />
  <xsl:choose>
    <xsl:when test="contains($str, '-')">
      <xsl:value-of select="concat(format-number(substring-before($str, '-'), substring(substring('2000', 4 - string-length(substring-before($date-format, '-'))), 1, string-length(substring-before($date-format, '-')))), '-')"/>
      <xsl:call-template name="dateFormat">
        <xsl:with-param name="str" select="substring-after($str, '-')" />
        <xsl:with-param name="date-format" select="substring-after($date-format, '-')" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="format-number($str, substring(substring('2000', 4 - string-length($date-format)), 1, string-length($date-format)))"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

I'll also format YYYY-MM-DD.

Cheers,
