Making sorted balanced two-column tables from one-column data from unsorted data

[Tom Chmielenski <Tom dot Chmielenski at bentley dot com>]

I am trying to create a two column table from unsorted data.
The idea is very similar to the XSL FAQ: Making balanced two-column tables
from one-column data (see
http://www.dpawson.freeserve.co.uk/xsl/N7450.html#N13669 ).  However, my
data is initially unsorted.  
I initially tried adding  <xsl:sort> as a subelement to <xsl:for-each>, and
I get the following results (using MSXML3):

	A H
	B E
	C G
	D K
	E J
	F

The first column is sorted and is correct, the second column is not.  Looks
like  "select=$comp-list[$here+$half]" is using the unsorted list of
COMPONENTS rather than the sorted list.  This kinda makes sense.  

So I tried to create a variable that contains the sorted list of nodes like
this, but this yields no nodes:
	  <xsl:variable name="sorted-comp-list">
  		<xsl:for-each select="COMPONENT">
			<xsl:sort select="." />
		</xsl:for-each>
	  </xsl:variable>

Anybody know of a way to create a sorted list of nodes and be able store in
a variable for later use?

Thanks in advance.
