Looking at the code that you posted the other day, it seems that you
need the sorted position to be able to work out whether or not to
generate some output.  E.g.:

------------------------------------------------------------
						<xsl:if
test="ancestor::property[@type='MoveAssetSuccess']/descendant::property[
@name='mfAccNo'] != $lastacc">
							<fo:block
space-before.optimum="5pt" space-after.optimum="5pt" font-size="10pt"
text-align="left">
	
<xsl:apply-templates
select="ancestor::property[@type='MoveAssetSuccess']/descendant::propert
y[@name='mfAccNo']"/>
							</fo:block>
						</xsl:if>
------------------------------------------------------------

If that is the case, then your problem could be recast as needing to
group certain nodes and only needing to generate some output at the
start of the group.

There were numerous folk remedies for grouping developed for XSLT 1.0
that people have been happy to forget now that there's XSLT 2.0.  Using
XSLT 2.0 is generally better, unless it's not an option.

Resources for XSLT 1.0 grouping include:

 - EXSLT set functions [1]

 - Jeni Tennison's Grouping pages [2]

 - Dave Pawson's XSLT FAQ [3]
