It's often been suggested that there should be char-to-unicode and
unicode-to-char functions, which would allow you to write

<xsl:for-each
    select="for $i in char-to-unicode('a')
                   to char-to-unicode('z')
            return unicode-to-char($i)">
...
</xsl:for-each>

That would be explicitly based on Unicode values; finding all the characters
that are between 'a' and 'z' in your default collating sequence sounds like
a more difficult challenge.
