The complete template might look like this:

  <xsl:template match="Products">
    <xsl:copy>
      <xsl:copy-of select="@*, Manager" />
      <xsl:for-each-group select="Product" group-by="@id">
        <xsl:for-each select="current-group()">
          <xsl:sort select="number(rank)" order="descending"/>
          <xsl:if test="position() = 1">
            <xsl:copy-of select="."/>
          </xsl:if>
        </xsl:for-each>
      </xsl:for-each-group>
      <xsl:copy-of select="* except (Manager union Product)" />
    </xsl:copy>
  </xsl:template>
