[xsl] Is this a sorting bug in xalan 6.4.0?

[Stan Dyck <sgd@xxxxxxxxxxxx>]

Can anyone explain this apparent bug in xalan 2.4.0? Given...

<NameList>
	<Record><Name>A</Name></Record>
	<Record><Name>AAL</Name></Record>
	<Record><Name>Amanda</Name></Record>
	<Record><Name>Amy</Name></Record>
	<Record><Name>A Maureen</Name></Record>
</NameList>

...and applying the following stylesheet...

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" indent="yes"/>

<xsl:variable name="lower" select="'abcdefghijklmnopqrstuvwxyz'"/>
<xsl:variable name="upper" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

<xsl:template match="NameList">
	<xsl:comment><xsl:value-of select="system-property('xsl:vendor')"/>
	</xsl:comment>
	<table>
		<xsl:apply-templates select="Record">
			<xsl:sort select="translate(Name, $lower, $upper)"/>
		</xsl:apply-templates>
	</table>
</xsl:template>

<xsl:template match="Record">
	<tr><td><xsl:value-of select="Name"/></td></tr>
</xsl:template>
</xsl:stylesheet>

I get...

<!--Apache Software Foundation--><table>
<tr>
<td>A</td>
</tr>
<tr>
<td>AAL</td>
</tr>
<tr>
<td>Amanda</td>
</tr>
<tr>
<td>A Maureen</td>
</tr>
<tr>
<td>Amy</td>
</tr>
</table>

...using xalan, and (for example)...

<!--SAXON 6.4.1 from Michael Kay--><table>
   <tr>
      <td>A</td>
   </tr>
   <tr>
      <td>A Maureen</td>
   </tr>
   <tr>
      <td>AAL</td>
   </tr>
   <tr>
      <td>Amanda</td>
   </tr>
   <tr>
      <td>Amy</td>
   </tr>
</table>

...using saxon. It looks like xalan is removing the space between "A" 
and "Maureen", causing it to sort below Amanda. It looks like a bug to 
me, agreed? I couldn't find similar examples on either this list's 
archives or on xalan's bug list.

p.s. Note, I can work around the bug by replacing my upper and lower 
variables with...

<xsl:variable name="lower" select="' abcdefghijklmnopqrstuvwxyz'"/>
<xsl:variable name="upper" select="'_ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
