grr you're right of course. I didn't want to construct elements at all
here but had to due to the restriction on / having sequence of nodes on
the left hand side. (The other way is to use for rather than / but
that's what the OP used:-)

course it's easier in xslt where you can go
<xsl:for-each select="( 'cat', 'dog', 'apple')">
<xsl:sort select="."/>
<word  n="{position()}"><xsl:value-of select="."/></word>
