Re:  finding word count within a document
You would need to wrap the string in a document:

<xsl:variable name="input-doc" as="document-node()">
  <xsl:document>
     <xsl:value-of select="unparsed-text('input.txt')"/>
 </xsl:document>
</xsl:variable>

However this is pretty convoluted. If you define a function
word-count($string) then you can (a) use this in your accumulator, and (b)
apply it to a string directly, without any need for accumulators or document
nodes.

Personally I wouldn't use accumulators for this unless (a) you intend to use
streaming, or (b) there is a need to get the wordcount for arbitrary parts of
the document, e.g. chapters or sections.
