Hi Wendell,

The question I'd ask is what's @linkend. This of course depends on
what the context node is -- so we need to consider where this appears.

XSLT 2.0 functions work different from templates in that they don't
have a context node (or position or size) ... instead of relying on
being able to traverse from the context node to its @linkend
attribute, for example, you have to pass the node in and then traverse
to $node/@linkend.
Could this be an issue here? We need to see more code. But guessing
out of the blue (that is, guessing you are defining a function here) I
suppose you might try test="$cite-ref is
key('refs',$cite-ref/@linkend)[1]".
I'd like to have a function, but thought I'd start with a variable
first. I didn't post the code because it's a little hairy, but here
goes:
Step 1: template called from db:citation template
<xsl:template name="bib:format-citation">
<xsl:param name="output-format" as="xs:string"/>
<!-- create a temporary tree to hold the processing citations -->
<xsl:variable name="intermediate-citation">
<xsl:value-of select="$style-citation/cs:prefix"/>
<xsl:choose>
<!-- FIX: add additional sort modes -->
<xsl:when test="$sort_order-bib='author-year'">
<xsl:apply-templates select="."
mode="sort_citation_author-year">
<xsl:with-param name="output-format"
select="$output-format" as="xs:string" tunnel="yes"
/>
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="db:biblioref" mode="otherwise"/>
</xsl:otherwise>
</xsl:choose>
<xsl:value-of select="$style-citation/cs:suffix"/>
</xsl:variable>
<!--
create formatted output by running appropriate output mode on the
temporary
tree in the intermediate-citation variable
-->
<xsl:choose>
<xsl:when test="$output-format='latex'">
<xsl:apply-templates select="$intermediate-citation"
mode="output-latex"/>
</xsl:when>
<xsl:when test="$output-format='xhtml'">
<xsl:apply-templates select="$intermediate-citation"
mode="output-xhtml"/>
</xsl:when>
</xsl:choose>
</xsl:template>
Step 2: sort
<xsl:template match="db:citation" mode="sort_citation_author-year">
<!-- store citation for future use -->
<xsl:variable name="citation" select="."/>
<xsl:variable name="local-cite-style"
select="db:biblioref/@xrefstyle"/>
<xsl:variable name="idref"
select="db:biblioref/@linkend, course:reading/@refid"/>
<xsl:variable name="bibref"
select="$enhanced-biblist/mods:modsCollection/mods:mods[(_at_)ID=$idref]"/>
<bib:span class="citation">
<xsl:for-each-group select="$bibref" group-by="@bib:sort-on">
<xsl:sort select="current-grouping-key()"/>
<xsl:variable name="refs-for-author-sorted-by-year"
as="element(mods:mods)*">
<xsl:perform-sort select="current-group()">
<xsl:sort select="bib:year"/>
</xsl:perform-sort>
</xsl:variable>
<xsl:variable name="first-ref-for-author"
as="element(mods:mods)"
select="$refs-for-author-sorted-by-year[1]"/>
<xsl:variable name="last-ref-for-author" as="element(mods:mods)"
select="$refs-for-author-sorted-by-year[position() =
last()]"/>
<xsl:for-each-group select="$refs-for-author-sorted-by-year"
group-adjacent="bib:year">
<xsl:for-each select="current-group()">
<xsl:variable name="first-in-author-group"
select=". is $first-ref-for-author" as="xs:boolean"/>
<xsl:variable name="last-in-author-group"
select=". is $last-ref-for-author" as="xs:boolean"/>
<xsl:variable name="id" select="@ID"/>
<!-- earlier the cite-ref variable was defined as just
element(), but
for some reason this yielded an empty-sequence error in one
case -->
<xsl:variable name="cite-ref" as="element()*">
<xsl:sequence
select="$citation/db:biblioref[(_at_)linkend=$id]"/>
</xsl:variable>
<xsl:choose>
<xsl:when test="$citeclass='note-bib' or
$citeclass='note-nobib'">
<xsl:apply-templates select="." mode="citation_note">
<xsl:with-param name="first-in-author-group"
select="$first-in-author-group"/>
<xsl:with-param name="last-in-author-group"
select="$last-in-author-group"/>
<xsl:with-param name="local-cite-style"

</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="."
mode="citation_author-year">
<xsl:with-param name="first-in-author-group"
select="$first-in-author-group"/>
<xsl:with-param name="last-in-author-group"
select="$last-in-author-group"/>
<xsl:with-param name="local-cite-style"
select="$local-cite-style"/>
<xsl:with-param name="cite-ref" select="$cite-ref"
as="element()*"/>
</xsl:apply-templates>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:for-each-group>
<xsl:if test="position() != last()">; </xsl:if>
</xsl:for-each-group>
</bib:span>
</xsl:template>
Step 3:
<xsl:template match="mods:mods" mode="citation_author-year">
<xsl:param name="local-cite-style"/>
<xsl:param name="cite-ref" as="element()*"/>
<xsl:param name="citation"/>
<xsl:param name="first-in-author-group" as="xs:boolean"/>
<xsl:param name="last-in-author-group" as="xs:boolean"/>
<xsl:message>
<xsl:if test="$cite-ref is key('refs',@linkend)[1]">FIRST</xsl:if>
</xsl:message>
<bib:a class="citation" href="#{(_at_)ID}">
<xsl:if test="$first-in-author-group and
not($local-cite-style='year')">
<xsl:choose>
<xsl:when test="bib:noname-substitute">
<xsl:value-of select="bib:noname-substitute"/>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates
select="mods:name[mods:role/mods:roleTerm=$primary-contributors]"
mode="short"/>
</xsl:otherwise>
</xsl:choose>
<xsl:value-of
select="$style-citation/cs:entry/cs:creator/cs:suffix"/>
</xsl:if>
<xsl:value-of select="bib:year"/>
<xsl:value-of select="bib:year-suffix"/>
<xsl:if test="$cite-ref/@begin">

<xsl:value-of select="$cite-ref/@begin"/>
<xsl:if test="$cite-ref/@end">

<xsl:if test="not($last-in-author-group)">, </xsl:if>
