[xsl] How do you count nesting level

[J S Publications <admin@xxxxxxxxxx>]

Hi

I want to be able to work out how deep a given <title> is in a document. In 
the schema, <title> is always a direct descendant of a <section>. Given the 
following:

<collection>
	<section>
		<title>1</title>
		<title>2</title>
	</section>
	<section />
	<section>
		<title>3</title>
		<title>4</title>
		<section>
			<title>5</title>
		</section>
	</section>
</collection>

Title 1 and 2 are at level 1. Title 3 and 4 are at level 1. Title 5 is at 
level 2.

I have tried:

<xsl:template match="title" mode="DoIt">
	<xsl:param name="Depth" select="count(ancestor::*[section])" />
	<xsl:value-of select="$Depth" />
	<xsl:apply-templates mode="DoIt" />
</xsl:template>

But it doesn't seem to be working. What am I missing?
