Sorry for the buggy code. Here is a working version:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output indent="yes"/>
<xsl:template match="/">
<frequencies>
<xsl:for-each-group group-by="." select="
   for $w in tokenize(string(.), '[\s.?!,]+')[.] return lower-case($w)">
  <xsl:sort select="count(current-group())" order="descending"/>
  <word><xsl:value-of select="current-grouping-key(), '  -  ',
count(current-group())"/></word>
</xsl:for-each-group>
</frequencies>
</xsl:template>
</xsl:stylesheet>

(The predicate [.] elimitates the zero-length string)

Here's the start of the output for othello.xml:

<?xml version="1.0" encoding="UTF-8"?>
