RE: [xsl] problem with xsl:sort

<xsl:for-each> processes a set of nodes. The set of nodes is determined
by the select attribute. Saying select="." selects exactly one node.

The <xsl:sort> element determines the order in which the set of nodes
will be processed. For a set containing only one node, there is only one
possible order of processing, so <xsl:sort> is completely pointless.

I hope this makes it clearer.

I guess what you really wanted was for me to rewrite your code. You
picked the short straw on that - I'm not Jeni Tennison.
