I'm not sure why you're getting this error message, but if the sort key
for every record is "ARRIVED", then why bother sorting?

Subject: [xsl] xsl:variable problems: Error in XPATH Expression
What are the restrictions on using xsl:variables?
Am I not allowed to use it in an xsl:sort element?
I get the following error for the folowing xsl fragment:
<xsl:variable name="sortby">ARRIVED</xsl:variable>
<xsl:variable name="ordering">descending</xsl:variable>
<xsl:template match="REPORT">
<h1>
<xsl:value-of select="$sortby"/>
</h1>
<xsl:apply-templates select="INTERCHANGE">
<xsl:sort select="$sortby" order="ascending" /> <!--
ERROR HERE --> </xsl:apply-templates> </xsl:template>
----
Error in XPath Expression: Cannot use result tree fragment.
----
The <xsl:value-of select="$sortby"/> outputs "ARRIVED"
correctly, but dies inside the "sort" element.
