Re: insert.link.page.number in xsl stylesheets

Hi Kevin,

Indeed, it looks like the "select:" mechanism in @xrefstyle was never 
implemented for link element page references, only for xrefs. This will 
require customizing the generated text instead.  See 
http://www.sagehill.net/docbookxsl/CustomGentext.html#CustomGenText


You can change the default (unspecified) style by adding this to your 
customization layer:


<xsl:param name="local.l10n.xml" select="document('')"/>
<l:i18n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0">
   <l:l10n language="en">
     <l:context name="xref">
       <l:template name="page.citation" text=" (page %p)"/>
     </l:context>
   </l:l10n>
</l:i18n>


If you don't want to alter the default style, the named style mechanism 
does work, so you could add a this  instead (note the @style attribute):

.

<xsl:param name="local.l10n.xml" select="document('')"/>
<l:i18n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0">
   <l:l10n language="en">
     <l:context name="xref">
       <l:template name="page.citation" style="mystyle" text=" (page %p)"/>
     </l:context>
   </l:l10n>
</l:i18n>


Then you would get your style if you specify <link xrefstyle="mystyle">, 
otherwise you get the default.
