Re: combining multiple documents

With respect,

               <!-- But actually we wanted to pass the extra for use
here in the second instance of "document" -->

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()"/>
