Thank you David for reply..

The example you have given works.. But I have a
doubt..

For e.g. if XML file is -
<root>
  <foo>xxx</foo>
  <bar>yyy</bar>
</root>

And stylesheet is -
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="html" indent="yes" />

<xsl:template match="bar" name="bar">
 <span><xsl:apply-templates/></span>
</xsl:template>

<xsl:template match="foo">
 <div class="foo"><xsl:call-template
name="bar"/></div>
</xsl:template>

</xsl:stylesheet>

When I run the transform with Saxon 8.1 , I get the
output -
<div class="foo"><span>xxx</span></div>
<span>yyy</span>

When context node is <bar> , the 1st template is
invoked and it generates output <span>yyy</span> ,
which is perfectly fine..

But when context node is <foo> , the 2nd template is
invoked.. which further calls <xsl:call-template
name="bar"/> . My doubt is - when <xsl:call-template
name="bar"/> instruction is executed from 2nd
template, how(and is it supposed to according to
spec..) is the context propagated to the 1st
template.. I am surprised why <xsl:apply-templates/>
is generating output xxx, when called from 2nd
template.. 

Can you please explain the flow of control in template
<xsl:template match="foo"> ? 

Regards,
Mukul
