<xsl:function name="f:country" as="xs:string">
 <xsl:param name="a" as="element()"/>
 <xsl:choose>
  <xsl:when test="$a/cross-ref">
   <xsl:sequence select="key('country', $a/cross-ref/@refid,root($a))/tokenize(.,',\s+')[last()]"/>
  </xsl:when>
  <xsl:otherwise>
     <xsl:sequence select="$a/following-sibling::affiliation[1]/tokenize(.,',\s+')[last()]"/>
  </xsl:otherwise>
 </xsl:choose>
