character in procedure list heading in html

Hello there,

 

I’m trying to put a new charcter in the
procedure list heading.

But using the entity does not work. I’m trying:

 

<xsl:template
name="symboled.procedure.heading">

    <xsl:param name="object"
select="."/>

    <xsl:param name="title">

        <xsl:apply-templates
select="$object" mode="object.title.markup">

            <xsl:with-param
name="allow-anchors" select="1"/>

        </xsl:apply-templates>

    </xsl:param>

 

    <p class="title">

        <b>

            <xsl:text>&rtrif;
</xsl:text>

            <xsl:copy-of
select="$title"/>

        </b>

    </p>

</xsl:template>

 

But the &rtrif; is an unknown entity.

Can I use these entities in my chm/html files?

 

Thanks

            Hinrich
