  I assume you mean "value" instead of "measure" above.  Try this:

<xsl:variable name="mysum">
  <xsl:call-template name="sum-rounded-values">
    <xsl:with-param name="value" select="//value" />
  </xsl:call-template>
</xsl:variable>
<xsl:value-of select="format-number($mysum)" />

...

<xsl:template name="sum-rounded-values">
  <xsl:param name="value" />
  <xsl:param name="_sum" select="0" />
  <xsl:choose>
    <xsl:when test="value">
      <xsl:call-template name="sum-rounded-values">
        <xsl:with-param name="value" select="$value[position() > 1]" />
        <xsl:with-param name="_sum" select="$_sum +
                                            format-number($value[1],
                                                          '##')" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="$_sum" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

  You can further enhance it by making the pattern '##' an argument or 
using modes instead of call-template.  HTH!
