Example:
<doc>
<p>a <citation/> and a <footnote>and a <citation/> in a
footnote</footnote> and a <citation/></p>
</doc>
Correctly working stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:bib="http://purl.org/NET/xbiblio/citeproc";
exclude-result-prefixes="xs bib" version="2.0">
<xsl:template match="doc">
<list>
<xsl:apply-templates
select="//footnote|//citation[not(ancestor::footnote)]"/>
</list>
</xsl:template>
<xsl:template match="p">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="footnote">
<number>
<xsl:value-of select="bib:footcite(.)"/>
<xsl:apply-templates select="citation"/>
</number>
</xsl:template>
<xsl:template match="citation">
<number>
<xsl:value-of select="bib:footcite(.)"/>
</number>
</xsl:template>
<xsl:template match="citation[ancestor::footnote]">
<nonumber/>
</xsl:template>
<xsl:function name="bib:footcite" as="xs:string">
<xsl:param name="footciteable" as="element()"/>
<xsl:for-each select="$footciteable">
<xsl:number level="any" select="."
count="footnote|citation[not(ancestor::footnote)]"/>
</xsl:for-each>
</xsl:function>
</xsl:stylesheet>
Yields this output:
<list>
<number>1</number>
<number>2<nonumber/>
</number>
<number>3</number>
</list>
So this the output that you want? I think this illustrates the point that if
your count pattern matches the same nodes as the ones you select for
numbering, you will get consecutive numbers.
Now, if I change the function to this:
<xsl:function name="bib:footcite" as="xs:string">
<xsl:param name="footciteable" as="element()"/>
<xsl:number level="any" select="$footciteable"
count="footnote|citation[not($footciteable/ancestor::footnote)]"/>
</xsl:function>
I get:
<list>
<number>1</number>
<number>2<nonumber/>
</number>
<number>4</number>
</list>
I don't understand why you've changed a "correctly working stylesheet".
Saxon (8.4) will not allow me to remove the $footcitable on the count,
nor to add it as context to the footnote.
Your original "correctly working stylesheet" didn't have $footcitable in the
count pattern, and works with Saxon 8.4, so I don't understand what you mean
by this. And I don't know what you mean by "add it as context to the
footnote" either!
(But thanks for putting together a complete example.)
