Customizing the XSL indexterm templates is a serious challenge.
Those are among the most complex templates in the stylesheets.
But you can avoid that problem entirely.

Your file is a classic case of profiling, except you
are using your own tags.  Here is a stylesheet that
does an identity transform, except that it maps your
custom language tags to standard phrase elements with
a lang attribute.  Then you can use the profiling
stylesheet with the profile.lang stylesheet parameter
to process the result. 

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="1.0">

<xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:apply-templates/>
   </xsl:copy>
</xsl:template>

<!-- convert language tags to phrase with lang attribute --> 

<xsl:template match="translations">
      <xsl:apply-templates/>
</xsl:template>

<xsl:template match="english">
     <phrase lang="en">
	 <xsl:apply-templates/>
     </phrase>
</xsl:template>

<xsl:template match="spanish">
     <phrase lang="es">
	 <xsl:apply-templates/>
     </phrase>
</xsl:template>

<xsl:template match="french">
     <phrase lang="fr">
	 <xsl:apply-templates/>
     </phrase>
</xsl:template>

</xsl:stylesheet>

Then the transformation is done in four steps
(maybe in a Makefile):

	xsltproc \
	-output mykone.tmp.xml \
	the_above_stylesheet.xsl \
	mykone.xml

	xsltproc \
	-output mykone.profiled.xml \
	--stringparam profile.lang "es" \
	../docbook-xsl-1.62.4/profiling/profile.xsl \
	mykone.tmp.xml
	
	xsltproc \
	-output mykone.fo \
	--stringparam fop.extensions 1 \
	../docbook-xsl-1.62.4/fo/docbook.xsl \
	mykone.profiled.xml

	fop.sh mykone.fo mykone.pdf

It is a different approach, but a lot easier to
implement than customizing the index templates.
And it happens to work for all other elements in
your documents as well.
