y, nice :)
should be an easy template.
but if figures with informaltables inside are covered ... no idea :)

nice :)

but we are using xsltproc! :(

first we used saxon, but it didnt work with chunking (found error in
chunk-code.xsl)
is this a known bug?

i installed xalan now, but:

file: //gentext.xsl; Line 153; Column 61; XSLT-Error
(javax.xml.transform.TransformerException): Variable accessed before it is
bound!

<xsl:template match="*" mode="object.xref.template">
  <xsl:param name="purpose"/>
  <xsl:param name="xrefstyle"/>
  <xsl:param name="referrer"/><!--may i set a default value here?-->

  ...

        <xsl:with-param name="purpose" select="$purpose"/>
        <xsl:with-param name="xrefstyle" select="$xrefstyle"/>
        <xsl:with-param name="referrer" select="$referrer"/> <!--LINE 153-->
      </xsl:call-template>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

thx
