Bruce,

We might have to ask Mike, Dimitre or someone else practiced in the art of XSLT 2.0 functions to confirm this, but

At 06:18 PM 5/28/2005, you wrote:
Yes. Unfortunately, the "ibid" handling is now being applied to both
the first and the following duplicate citation (it should only be for
the latter).  I can't figure out why that should be the case.

Here's my function:

  <xsl:function name="bib:ibid" as="xs:boolean">
    <xsl:param name="citation" as="node()"/>
    <xsl:value-of select="count($citation/db:biblioref)=1 and
$citation/db:biblioref/@linkend =
$citation/preceding::db:citation/db:biblioref/@linkend"/>
  </xsl:function>

The only thing I can suggest here is that perhaps the xsl:value-of here does not return a Boolean value, as you appear to expect it to, but a string, which perhaps always casts to Boolean true() (because both the strings "true" and "false" have non-zero length). That's the way it would work in 1.0, and under value-of in Mike's XSLT 2.0 book it reads that the instruction "constructs a text node", which would seem to be similar.

Maybe you want to try an xsl:copy-of there instead? Or the new favorite, xsl:sequence.

Cheers,
Wendell
