  <xsl:attribute name="bgcolor">
    <xsl:if test="state = 'on' and ack = 'on'">#ff0000</xsl:if>
    <xsl:if test="state = 'on' and ack = 'off'">#008000</xsl:if>
  table contents

In XSLT 2.0, you can do it all within an attribute value template if you

<tr bgcolor="{if (....) then '#ff0000' else ....}">
