Hi,

In addition to what Michael already discussed:

It's called from the "apply-set" template
	<tr>
		<xsl:apply-templates select="$set"/>
	</tr>
With each recursion, a new $set variable is used, which gets its
initial value here:
	<xsl:with-param name="set" select="$set/*"/>
The new set of nodes is selected to contain all the child elements
(note the /*) of the nodes in the current set. On the very last
recursion $set contains the "Col" elements and those match the
template in question.
The fact that there are no more child elements is used to stop the
recursion and get the call closed. If you look at the point in
"apply-set" where we called it again
	<xsl:call-template name="apply-set">
		<xsl:with-param name="set" select="$set/*"/>
	</xsl:call-template>
and where we return from the "active" call, you see that "apply-set"
has already done all it should do, so closing it silently.

Hope this helps,

Manfred
