Just to make sure I'm not just doing something else which causes
Xalan (under cocoon 2.1) to mess up when <xsl:sort select="name()" />
is switched to the promising sounding xpath suggested by David Carlisle...
here is the stylesheet in (abbreviated) full.  Any suggestions for
acheiving the same result appreciated.  (or pointing out if I'm just
missing something completely obvious!) The document in question will
always have ant|res|prayer as its root element.

---------
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan" exclude-result-prefixes="xalan" >
<xsl:output method="html" />
  <xsl:variable name="id"><xsl:value-of select="/ant/@id|/res/@id|/prayer/@id"/></xsl:variable>
  <xsl:variable name="mss" select="document('../../mss/mss.xml')"/>
    <!-- file containing manuscript //witness/@shortname -->

<!-- just match root node -->
<xsl:template match="/">
  <xsl:apply-templates/>
</xsl:template>


<xsl:template match="/ant|/res|/prayer">
<html> <head>
<title>Critical Edition <xsl:value-of select="$id"/></title>
<link href="/styles/cursus.css" type="text/css" rel="stylesheet"> </link>
</head>
<body>
<h1>Critical Edition of <xsl:value-of select="$id"/></h1>
    <xsl:variable name="unique-wit-list">
      <xsl:call-template name="unique-token-list">
       <xsl:with-param name="str">
       <xsl:for-each select="//aBody|//rBody|//pBody">
       <xsl:text> </xsl:text> <xsl:value-of select="@wit"/><xsl:text> </xsl:text>
       </xsl:for-each>
       </xsl:with-param>
      </xsl:call-template>
    </xsl:variable>
<form action="{concat('/cursus/test/ind/', $id)}">
See just the reading for:
<select name="wit" onchange="this.form.submit()" >

  <xsl:for-each select="xalan:nodeset($unique-wit-list)/*">
  <xsl:sort select="name()"/>
<!-- <xsl:sort select="$mss//witness[@sigil=name(current())]/@shortname" /> -->
<!-- if the above two xsl:sorts are swapped, it dies, if not it sorts by the $token which
     is the same as sorting by $sigil -->
   <xsl:variable name="sigil" select="name()"/>
   <xsl:variable name="shortname" select="$mss//witness[@sigil=$sigil]/@shortname"/>
  <option value="{name()}"><xsl:value-of select="$shortname"/></option>
 </xsl:for-each>

</select>
<input type="submit" value=" Change"/>
</form>
<hr />
     <xsl:apply-templates/>
     <hr />

 Orthogonal views:
       <a href="{concat($id,'?cocoon-view=content')}">Content</a><xsl:text>  </xsl:text>
       <a href="{concat($id,'?cocoon-view=pretty-content')}">Pretty content</a><xsl:text>  </xsl:text>
</body>
</html>
</xsl:template>

<xsl:template name="unique-token-list">
 <xsl:param name="str"/>
 <xsl:param name="nl"/>
<xsl:variable name="token"
select="substring-before(concat(normalize-space($str), ' '), ' ')"/>
<xsl:choose>
<xsl:when test="string-length($token) > 0">
 <xsl:call-template name="unique-token-list">
   <xsl:with-param name="str" select="substring-after($str, $token)"/>
   <xsl:with-param name="nl">
    <xsl:copy-of select="xalan:nodeset($nl)/*"/>
    <xsl:if test="count(xalan:nodeset($nl)/*[name()=$token]) = 0">
    <xsl:element name="{$token}"/>
    </xsl:if>
    </xsl:with-param>
    </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
     <xsl:copy-of select="xalan:nodeset($nl)"/>
     </xsl:otherwise>
     </xsl:choose>
</xsl:template>



<!-- And then a whole bunch of templates just to match elements
     and replace with classed spans or divs styled in the CSS -->

</xsl:stylesheet>

Suggestions?
