Define a global variable
<xsl:variable name="root" select="/"/>
and use $root as the third argument of key().

Subject: [xsl] Key lookup without context.
Hello,
I have a 'context-free' function which does a key() lookup.
However, saxon is complaining:
SXWN9009: Cannot select a node here: the context item is undefined
Question: How can I say: "Start a key lookup from the root of
the file"?
I tried select="\\key('myKey'...." but this didn't work.
So I have:
<xsl:key name="myKey" match="books/book/...." use="..."/>
<xsl:function name="...." as="xs:double"> <xsl:param name="input"/>
<xsl:for-each select="key('myKey',$input)">
processing goes here
</xsl:for-each>
</xsl:function>
