DOCBOOK-APPS: XML stylesheet question - overriding title on titlepage

Greetings,

Under version 1.24 of the stylesheet package, I had this working.
Upgrading to 1.29, it seems to have broken.  Or maybe my solution
was broken to begin with and only now being revealed.

I'm trying to override various attributes on the titlepage, 
including author, copyright and title.  The first two 
are working as I'd expect, but my title override is being
ignored.  

This works:

<xsl:template match="author" mode="titlepage.mode">
  <fo:block font-size="14pt" 
            font-weight="bold" 
	    text-align="center"
	    font-family="sans-serif">
    <xsl:call-template name="person.name"/>
  </fo:block>
  <xsl:apply-templates mode="titlepage.mode"
   select="affiliation"/>
</xsl:template>

I get the following output in file.fo:

<fo:block>
  <fo:block font-family="sans-serif" text-align="center" 
  font-weight="bold" font-size="14pt">Liza Daly</fo:block>
</fo:block>

However, the same principle applied to the title does
not:

<xsl:template match="title" mode="titlepage.mode">
  <fo:block font-size="20pt"
            font-weight="bold"
            space-before.optimum="8em"
	    font-family="sans-serif"
	    text-align="center"
	    padding-bottom="8em">
    <xsl:apply-templates mode="titlepage.mode"/>
  </fo:block>
</xsl:template>

In file.fo, I get:

<fo:block font-family="Helvetica" font-weight="bold" 
font-size="24.8832pt" keep-with-next="always" margin-left="-4pc">
  <fo:block>Title</fo:block>
</fo:block>

Am I going about this the wrong way, or is there a bug?

(I'm processing with Xalan 1.2.2)

Thanks,

--Liza
