Ah, okay. (It helps to be able to see the source.)

So perhaps your calling template would select the appropriate cs:reftype 
element in the config file to process:

<xsl:apply-templates name="style-biblio" 
select="$styles/cs:citationstyle/cs:content/cs:bibliography[@author-as-sort-order='yes']/cs:entry/cs:reftype[@name='book']">
  <xsl:with-param name="source" select="."/>
</xsl:apply-templates>

And then

<xsl:template match="cs:reftype">
  <xsl:param name="source"/>
  <xsl:apply-templates>
    <xsl:with-param name="source" select="."/>
    <!-- the parameter passing shouldn't be necessary w/ XSLT 2.0
         'tunneling parameters' -->
  </xsl:apply-templates>
</xsl:template>

<xsl:template match="cs:title">
  <xsl:param name="source"/>
  <!-- do your title thing here, grabbing data from
       $source (the mods source) as necessary -->
  ...
</xsl:template>

etc.

Basically you're jumping back and forth between the trees, carrying the 
data you need from one to the other so you can "graft" the branches.

Sorry for the confusion here -- it's not the mods:titleInfo that has the 
wrong name; it's the template itself. And you don't want to select a 
*template* for processing....
