Before I run off to test if parameter passing will meet my need let me
ask an obvious question. By their nature keys can contain multiple
elements. My example was meant to illustrate the passing of sets of
such elements not individual elements.
Your proposed solution allows me only to pass one element of the key,
when I want the entire contents of the key. Is there something I missed?
With respect,
Steven

If you want to pass that. then pass it as a parameter.
<xsl:apply-templates
select="doc(@file)"/>
don't do that, do this
<xsl:apply-templates
select="doc(@file)/document">
<xsl:with-param name="extra"
select="key('extra','introduction')"/>
</xsl:apply-templates>
aand declare this as a parameter to /document (rather than /, hence
teh
change in the select above)
<xsl:template
match="/document">
<xsl:param name="extra" select="()"/>
then you can use <xsl:apply-templates select"$extra"/>
wherever you need to use it.
couple of unrelated points
<xsl:template
match="/document">
<xsl:choose>
It's usually simpler to rewrite a template that just consistes of an
xsl:choose as separate templates.
<xsl:for-each
select="key('extra','introduction')">
<xsl:apply-templates
select="child::node()"/>
</xsl:for-each>
could more simply be written as
<xsl:apply-templates select="key('extra','introduction')/node()"/>
