I think it should be sufficient to use
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
Age exists=
<xsl:call-template name="subtemp">
<xsl:with-param name="parm"
select="//myelement[(_at_)name = 'karl']"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="subtemp">
<xsl:param name="parm"/>
<xsl:value-of select="exists(@age)"/>
</xsl:template>
</xsl:stylesheet>
since the return value of a named template is inserted in the place,
where you call your named template.
Alternativly you can also put your named template call in a variable,
which then gets the returned value assignd.
BTW, exit() should be exists()...

Betreff: [xsl] How to return values from sub-template?
Sorry for this newbie question but I didn't found a hint in
tutorials on how to return back parameter values from
sub-templates. Assume the following situation.
I want to pass back the boolean (or other values in other
scenarios) value if the attribute "age"
exists in a node "myelement" with the attribute name="karl".
Yes, I know, THIS sample could be coded easier within one
template but my sample is only a simplified version for a
complex scenario where two templates are required.
Again, how can I access the value of the variable myval from
the calling template?
Thank you
Matt
<xsl:template match="/">
<xsl:call-template name="subtemp">
<xsl:with-param name="parm" select="//myelement[(_at_)name =
'karl']" />
</xsl:call-template>
Age exists=<xsl:value-of select="$myval" /> <!-- does not
work --> </xsl:template>
<xsl:template name="subtemp">
<xsl:param name="parm" />
Hello
<xsl:variable name="myval" select="exist(@age)" />
return $myval
</xsl:template>
