There is a "slight" difference: I didn't use key() inside the
expression in the "use"  attribute (I believe the error is raised to
prevent cirkular key definition) -- and the below transformation is
working with Saxon:

<xsl:stylesheet version="1.0" xmlns:xsl="";>
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:key name="kRendByUsageGi" match="rendition"

 <xsl:template match="/">
  <xsl:copy-of select="key('kRendByUsageGi', 'p')/text()"/>
  <xsl:copy-of select="key('kRendByUsageGi', 'emph')/text()"/>
