Re: [xsl] Sorting + unique copy problem

["Thomas B. Passin" <tpassin at mitretek dot org>]

In fact, your stylesheet does work except for one thing.  It isn't
well-formed because the <form> element isn't closed.  You need to add the
closing tag for it - which you need even in html - and preferably also
declare

<xsl:output method='html'/>

After I made that fix, the select box does have the keywords sorted
alphabetically as you want.  Without the fix, the stylesheet cannot run.
