<xsl:value-of
select="document('data-reference.xml')/Data-Set/Data[(_at_)reference-
id = '12543']/value"/>
<xsl:for-each select="document('data-reference.xml')">
<xsl:value-of select="key('reference-value','12543')/value"/>
</xsl:for-each>
One of the few improvements that Xpath2 has over Xpath1 is that you
will be able go
<xsl:value-of
select="document('data-reference.xml')/key('reference-value','12543')/value"/>
and get rid of the for-each step.
