I don't know the origins of this thread but that looks highly dubious
- the key lookup would be the string value of all of the <Channel>
elements in s.xml.

If this is XSLT 1.0 then the pattern is:

<xsl:variable name="this" select="/">
<xsl:variable name="sDoc" select="document('s.xml')"/>

<xsl:for-each select="$sDoc//Channel">
  <xsl:variable name="lookup" select="."/>
  <xsl:for-each select="$this">
    <xsl:apply-templates select="key('chnam', $lookup)"/>

In 2.0 its much easier because you don't have to maintain a pointer to
the original source XML, and you have the slash operator, so the
equivalent is:

<xsl:apply-templates select="$sDoc//Channel/key('chnam', ., /)"/>
