In your xslt it is possible to call Java code. Here is how I do it using Xalan and JSword:
  <!-- Create a versification from which verse numbers are understood -->
  <xsl:variable name="v11nf" select="jsword:org.crosswire.jsword.versification.system.Versifications.instance()"/>
  <!-- Create a global key factory from which OSIS ids will be generated -->
  <xsl:variable name="keyf" select="jsword:org.crosswire.jsword.passage.PassageKeyFactory.instance()"/>
  <!-- Create a global number shaper that can transform 0-9 into other number systems. -->
  <xsl:variable name="shaper" select="jsword:org.crosswire.common.icu.NumberShaper.new()"/>
  <xsl:template match="verse" mode="print-notes">
    <xsl:if test=".//note[not(@type) or not(@type = 'x-strongsMarkup')]">
      <xsl:variable name="versification" select="jsword:getVersification($v11nf, $v11n)"/>
      <xsl:variable name="passage" select="jsword:getValidKey($keyf, $versification, @osisID)"/>
      <a href="#{substring-before(concat(@osisID, ' '), ' ')}">
        <xsl:value-of select="jsword:getName($passage)"/>
      <xsl:apply-templates select=".//note" mode="print-notes" />

I invoke xalan.jar (or what is embedded in java), with jsword jar in the classpath, to do the transformation.

The syntax is particular to xalan. There is a different syntax for saxon. Haven't tried it though.

There are Java bindings for the SWORD library. Troy can give more on this. They might dig deep enough to expose the SWORD parser in all of it's glory.

A proper reference in OSIS is wrapped in <reference osisRef="the OSIS reference">the text reference</reference>
A cross reference not is <note type="crossReference">one or more cross references</note>

It is these two things together that produce the reference.

Basically, the reference element says to ignore the text reference and use the osis reference instead.
