Problem using the doucument function()

Hi there,

How do I get back to using a context outside of the current XSL?-->

<xsl:apply-templates select="document('')/*/config/tube-line" />


<xsl:template match="tube-line">
  <xsl:value-of select="@hex"/>
<!--+ Then I want to use an apply-templates to match a node which is in
an XML 
    | (which has been aggregated in by Cocoon). It is a node I would get
    if I was not using the 
    | the document('') at the initial call. 
  <xsl:apply-templates select="/data/headline"/>
</xsl:template>
