Re: [docbook-apps] Collecting glossentries in glossary database

[Georges Schmitz <georges.schmitz@heitec.de>]

Thank you for your valuable help, especially the tip of using 2 separate 
keys and thus calculating two intersections at once seems very elegant 
to me.

There was just a small mistake, the last use of the key function should be

    key('indirectly-referenced', @id)/../../@id))

To allow for "condionality", would it be enough to perform a test with 
function-available() and if negative, just processing the original 
glossary? Because I wouldn't know, how to come around with the problem 
of using a temporary tree containing a filtered glossary.

  <xsl:choose>
    <xsl:when test="function-available('exsl:node-set')">
      <xsl:for-each select="exsl:node-set($collected.glossary)/glossary">
        <xsl:call-template name="make-glossary"/>
      </xsl:for-each>
    </xsl:when>
    <xsl:otherwise>
      <xsl:message>+++ Function 'exsl:node-set()' not available. 
Processing glossary in ordinary way. +++</xsl:message>
      <xsl:call-template name="make-glossary"/>
    </xsl:otherwise>
  </xsl:choose>

I will continue working on it (when I get time), especially introducing 
some parameter to switch sorting on/off and FO should work too.

Thanks for the help so far,
Georges
