RE: Usage of key inside a for loop of a RTF does not w

The key() function selects nodes in the document that contains the context
node. If the context node is in an RTF, it will select nodes in the RTF. If
you want to select nodes in a different document, first make that document
current. You can do this using xsl:for-each in XSLT 1.0, or in 2.0 by using
$doc/key('k', val).
