returning to initial document after changing context v

After having used the document function to get some node details from a 
config document, i need to return to the base document to continue 
processing. However, even though I have given an absolute path reference 
in the for-each statement, it seems to still be looking in the config 
document.


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0" 
xmlns:vbtn="http://www.virusbtn.com/namespaces/documents/issue/1.0/" 
xmlns:prism="http://prismstandard.org/namespaces/1.2/basic/" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:dcterms="http://purl.org/dc/terms/" 
xmlns:html="http://www.w3.org/1999/xhtml">
  <xsl:output method="xml" indent="yes"/>
  <xsl:variable name="autodate" 
select="document('/global/autodate.xml')/date"/>
  <xsl:variable name="month" select="$autodate/month[@position = 
/vbtn:article/vbtn:metadata/prism:number ]/@name"/>
  <xsl:variable name="index" 
select="document('/articles/virusbulletin/index.xml')/articles"/>
  <xsl:key name="articles" match="@filename" use="."/>
  <xsl:template match="/">
    <!-- article heading -->
    <h1>
      <xsl:value-of 
select="/vbtn:issue/vbtn:metadata/prism:publication"/>: <xsl:value-of 
select="/vbtn:issue/vbtn:metadata/prism:volume"/>
    </h1>
 
    <xsl:for-each select="$index/category">
      <section name="{@name}">
        <xsl:for-each select="/vbtn:issue/vbtn:content/vbtn:article">
          <xsl:value-of select="@id"/>
          <br/>
        </xsl:for-each>
      </section>
    </xsl:for-each>
 
  </xsl:template>
</xsl:stylesheet>

so <xsl:for-each select="/vbtn:issue/vbtn:content/vbtn:article"> should be 
referencing the original document rather than the config document. Is 
there a special function to return the context to the base document?
