For the second call to use the key on the first document you need to
do a bit of extra work in XSLT 1.0 eg

<xsl:variable name="val" select="val to use in key look up"/>
<xsl:for-each select="$first-doc">
  <xsl:apply-templates select="key('keyname', $val)"/>

...because the key will only ever be applied to the current document,
so you have to switch back to the first document before making the

XSLT 2.0 remedies this by providing a third argument to key to tell it
which document should be used:

key('keyname', value, $first-doc)

If that's a bit hard to follow, produce the test case and it will be
easier to show you with that.
