DOCBOOK: Decorating a template call?

[Michael Schuerig <schuerig@acm.org>]

I wanted to be able to have a way to make an author's name into a link 
and so added a url attribute to the author element. To process this new 
attribute, I had to customize the person.name template. The real work 
is still done in a slightly changed copy of the original template. The 
only change is the new name. Works fine, but the code duplication is 
not pretty:

<xsl:template name="person.name">
  <xsl:param name="node" select="."/>
  <xsl:choose>
    <xsl:when test="$node/@url">
      <a href="{$node/@url}">
        <xsl:call-template name="person.name.original">
          <xsl:with-param name="node" select="$node"/>
        </xsl:call-template>
      </a>
    </xsl:when>
    <xsl:otherwise>
      <xsl:call-template name="person.name.original">
        <xsl:with-param name="node" select="$node"/>
      </xsl:call-template>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

<xsl:template name="person.name.original">
  <!-- ...duplicated original template... -->
</xsl:template>

The duplication could be avoided if there was an indirection in the 
docbook stylesheets. But that doesn't seem right, either.
