Hi Wendell,

I have provided the comments to the second issue of Nested Concurrent-block 
nodes.

<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet exclude-result-prefixes="fo ms" version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:ms="urn:ms-xsl" 
xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<xsl:output method="xml" encoding="UTF-8" indent="yes"/> <xsl:template 
match="/ |node()"><xsl:copy>
 <xsl:apply-templates select="@*|node()"/>
</xsl:copy></xsl:template>
<xsl:template match="@*">
<xsl:copy>
</xsl:copy>
</xsl:template>

<xsl:key name="act-name" 
match="/processXML/process-definition/activity-state" use="@name"/>
<xsl:key name="act-name" match="/processXML/process-definition/decision" 
use="@name"/>
<xsl:key name="jname" match="/processXML/process-definition/join" 
use="@name"/>
<xsl:key name="con-name" 
match="/processXML/process-definition/concurrent-block" use="fork/@name"/>

<xsl:key name="forktransitions" 
match="/processXML/process-definition/concurrent-block/fork/transition" 
use="@to"/>
<xsl:template match="activity-state[(key('forktransitions',@name))]"/>
<xsl:template match="join" />


<xsl:template name = "template1"  
match="/processXML/process-definition/concurrent-block">
<xsl:copy>
<!-- To Copy  Concurrent-Blocks -->
<!-- From here concurrent-block starts -->
<!-- Loop starts picking the first concurrent-block -->
<xsl:for-each select="fork">
	<xsl:variable name="forkname" select="@name"/>
	<xsl:apply-templates 
select="/processXML/process-definition/concurrent-block/fork[@name=$forkname]"/>
	<xsl:for-each select="transition">
		<xsl:variable name="transname"><xsl:value-of select="@to"/></xsl:variable>
	  	<xsl:copy-of select="key('act-name', $transname)"/>
		<xsl:for-each select="key('act-name', $transname)">
			<xsl:variable name="joinname" select="transition/@to"/>
			<xsl:copy-of select="key('jname', $joinname)"/>
			<xsl:for-each select="key('act-name', $joinname)">
				<xsl:copy-of select="key('act-name', $joinname)"/>
			</xsl:for-each>
			<!-- Check whether this contains reference to another concurrent-block 
-->
			<!-- If it is present then call the template once again to process the 
concurrent-block subnode-->
			<xsl:for-each select="key('con-name', $joinname)">
				<xsl:call-template name="template1"  />
				<!-- This node is already populated here.. Hence it should not -->
				<!-- get populated when it is encountered in the above loop -->
			</xsl:for-each>
		</xsl:for-each>
	</xsl:for-each>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Hope this helps you understand the problem better.

Thanks
