Re: [docbook-apps] different gentext for olinks and xref

[Bob Stayton <bobs@sagehill.net>]

Yes, this can be done.  From your example, you want olinks to get the 
default styling, and you want to change the styling for xrefs.  You can 
do that in two steps in your customization layer:

1.  Add a gentext template with @style="xref" to your customization of 
local.l10n.xml:

  ...
  <l:context name="xref-number-and-title">
    <l:template name="section" text="%t" style="xref"/>
  </l:context>
  ...

2.  Customize the template in fo/xref.xsl that starts with:

  <xsl:match="xref" name="xref">

by changing how its variable named 'xrefstyle' is set.  I used:

  <xsl:variable name="xrefstyle">
    <xsl:choose>
      <xsl:when test="@role and not(@xrefstyle)
                      and $use.role.as.xrefstyle != 0">
        <xsl:value-of select="@role"/>
      </xsl:when>
      <xsl:when test="@xrefstyle">
        <xsl:value-of select="@xrefstyle"/>
      </xsl:when>
      <xsl:when test="local-name($target) = 'section'">xref</xsl:when>
      <xsl:otherwise></xsl:otherwise>
    </xsl:choose>
  </xsl:variable>

If an xref instance already has an @xrefstyle attribute, it uses it.  If 
not, then it tests if the target is a section, and if so sets the 
$xrefstyle variable to 'xref' to match the one you defined in the 
gentext template.  That special gentext template won't be used with olinks.
