[xsl] Setting table row color with xsl:choose and xsl:variable

[aevarga@xxxxxx]

I would like to set the color of a table row based on the value in one of the data fields.  The long way, which works, is to repeat the entire <tr><td> pattern for each value.  Isn't it possible using some variation of the following code to just read the field's value, assign a CSS class to the row and continue with template matching for the <td>'s?

<xsl:template match="Event">         
<xsl:choose>
  <xsl:when test="Required = 'yes'">
    <xsl:variable name="rowClass">calendarltred</xsl:variable>
  </xsl:when>
  <xsl:when test="Special = 'meeting'">
    <xsl:variable name="rowClass">calendaryellow</xsl:variable>
  </xsl:when>
  <xsl:when test="Special = 'candysale'">
    <xsl:variable name="rowClass">calendarltblue</xsl:variable>
  </xsl:when>
  <xsl:otherwise>
    <xsl:variable name="rowClass">default</xsl:variable>
  </xsl:otherwise>
</xsl:choose>
    <tr class="{$rowClass}">
      <td>
        <xsl:apply-templates select="DayOfWeek" />
        <xsl:apply-templates select="MonthName" />
        <xsl:apply-templates select="DayNum" />
      </td>
...

Thanks, Alan
