Change class attribute for titles based on value

[David Pratt <prattda@assiniboine.net>]

I want to change the value of the class attribute for sect2 titles 
based on the value of the title
so that I have finer control over CSS (style same level headers 
differently).

I have located the following templates in the titlepage.templates.xsl 
in the xhtml directory.  I am chunking my output
and using version 1.61.0.  sect2.titlepage.recto holds the output value 
that is currently being displayed (including the numbering it appears 
that I have turned on)
So I am having difficulty with what to compare.  For example I want to 
compare the title value against terms like summary, introduction etc.
so that the resulting div tag will be <div 
xmlns="http://www.w3.org/1999/xhtml" class="summary"> when title value 
equals summary,  <div xmlns="http://www.w3.org/1999/xhtml" 
class="introduction">  when title value equals introduction, and so on. 
  It is a bit complicated with the modes as well to determine
what to do.  Help appreciated.

<xsl:template name="sect2.titlepage.recto">
   <xsl:choose>
     <xsl:when test="sect2info/title">
       <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/title"/>
     </xsl:when>
     <xsl:when test="title">
       <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="title"/>
     </xsl:when>
   </xsl:choose>

   <xsl:choose>
     <xsl:when test="sect2info/subtitle">
       <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/subtitle"/>
     </xsl:when>
     <xsl:when test="subtitle">
       <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="subtitle"/>
     </xsl:when>
   </xsl:choose>

   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/corpauthor"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/authorgroup"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/author"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/othercredit"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/releaseinfo"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/copyright"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/legalnotice"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/pubdate"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/revision"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/revhistory"/>
   <xsl:apply-templates mode="sect2.titlepage.recto.auto.mode" 
select="sect2info/abstract"/>
</xsl:template>


<xsl:template name="sect2.titlepage">
   <div xmlns="http://www.w3.org/1999/xhtml" class="titlepage">    <-- 
this is the class attribute I want to change
     <div>
     <xsl:call-template name="sect2.titlepage.before.recto"/>
     <xsl:call-template name="sect2.titlepage.recto"/>                   
       <-- this parameter that holds the current title value
     </div>
     <-- <div>
     <xsl:call-template name="sect2.titlepage.before.verso"/>           
<-- commented out to suppress extra div tag in html output
     <xsl:call-template name="sect2.titlepage.verso"/>
     </div> -->
     <xsl:call-template name="sect2.titlepage.separator"/>
   </div>
</xsl:template>
