The difference is that Saxon 6.5.3 enters in the xsl:for-each loop below 
while Xalan 2.5.1 skips it.

File xsl/xhtml/autoidx.xsl, start line 116, DocBook  XSL 1.64.1:

<xsl:template match="indexterm" mode="index-primary">
   <xsl:param name="scope" select="."/>

   <xsl:variable name="key" 
select="normalize-space(concat(primary/@sortas, primary[not(@sortas)]))"/>
   <xsl:variable name="refs" select="key('primary', 
$key)[count(ancestor::node()|$scope) = count(ancestor::node())]"/>
   <dt>
     <xsl:value-of select="primary"/>
     <xsl:for-each select="$refs[generate-id() =
