In my site generation XSLT, an article has two titles. One, <title>
is used most of the time. But if a title named <shorttitle> exists,
that title is to be used in the index pages. Basically it's
necessary to /decide/ whether title should be applied, based on
whether shorttitle is there. The code looks like this, basically
suppressing title in favor of shorttitle:

<xsl:template match="header/title">
  <span class="indextitle">
    <xsl:if test="not(../shorttitle)">
        <a>
            <xsl:attribute name="href">
                <xsl:value-of select="$root"/>xpmag/<xsl:value-of select="../file"/>
            </xsl:attribute>
            <xsl:apply-templates/>
        </a>
    </xsl:if>
  </span>
</xsl:template>

<xsl:template match="header/shorttitle">
  <span class="indextitle">
    <a>
        <xsl:attribute name="href">
            <xsl:value-of select="$root"/>xpmag/<xsl:value-of select="../file"/>
        </xsl:attribute>
        <xsl:apply-templates/>
    </a>
  </span>
</xsl:template>

There may be a better way, but at the time I couldn't think of it,
and right now I don't see one offhand.
