RE: Creating index headers

This is a grouping problem, where the grouping key is the first character of
the value. For XSLT 1.0, use Muenchian grouping as described in
http://www.jenitennison.com/xslt/grouping, using substring(.,1,1) to compute
the grouping key.

With XSLT 2.0 you can write:

<xsl:for-each-group select="entry" group-by="substring(term, 1, 1)">
  <xsl:sort select="substring(term, 1, 1)"/>
  <h2><xsl:value-of select="substring(term, 1, 1)"/></h2>
  <a name="{substring(term, 1, 1)"/>
  <xsl:apply-templates select="current-group()"/>
</xsl:for-each-group>

This should work with Saxon 7.0.
