Oh, I see I misread your post. I thought you wanted to put the
table in the stylesheet, sorry.  Can't you just use a normal
key lookup?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:myns="uri.my.namespace"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:output method="text" />

  <xsl:key name="Keys" match="Keys/Key" use="@name" />
  
  <xsl:template match="/">
    <xsl:apply-templates select="/A/B/C/*"/>
  </xsl:template>
  
  <xsl:template match="Referrer">
    <xsl:value-of select="key('Keys', @ref)/@value"/>
  </xsl:template>

</xsl:stylesheet>
