I think that code from autoidx.xsl can be reused, namely from
generate-basic-template. For example following code will populate
variable $alphabetical with exactly one indexterm for each letter.
<xsl:variable name="terms"
select="//indexterm
[count(.|key('letter',
translate(substring(&primary;, 1, 1),
&lowercase;,
&uppercase;))
[&scope;][1]) = 1
and not(@class = 'endofrange')]"/>
<xsl:variable name="alphabetical"
select="$terms[contains(concat(&lowercase;, &uppercase;),
substring(&primary;, 1, 1))]"/>
So in order to get just letters something like the following code could
be used:
<xsl:for-each select="$alphabetical">
<rx:bookmark-label>
<xsl:value-of select="substring(&primary;, 1, 1)"/
</rx:bookmark-label>
</xsl:for-each>
