Ken,
I just ran your code and it produced the expected results.
Thanks,

Michael's answer gives you source document context of each item,
which can be very useful.

But to answer your specific question in the event that context is not 
needed:

Thankfully, it is straightforward to do something "for each" value in
a sequence:

<xsl:variable name="title" select="@title"/>
<xsl:variable name="ref" select="@ref"/>
<!--walk over each distinct value setting that value as the current node-->
<xsl:for-each select="distinct-values(........)">
  <Word title="{$title}" ref="{$ref}"><xsl:value-of select="."/></Word>
</xsl:for-each>

I hope this helps.
