I've still not managed to work out my grouping problem, but this is at
least most a solution for your's:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
    <xsl:template match="data">
        <data>
            <xsl:for-each-group select="record/subjects"
group-by="tokenize(., '; ')">
                <subject>
                    <xsl:value-of select="current-grouping-key()"/>
                </subject>
            </xsl:for-each-group>
        </data>
    </xsl:template>
</xsl:stylesheet>
