Subject: XPath problem with getting all ancestors

I've got a document like this:
<?xml version="1.0" encoding="utf-8"?>
<document>
<article>
<meta>
<title>Title</title>
</meta>
<content>
<headline>Headline</headline>
<para>
<note id="1">text</note>
</para>
</content>
</article>
</document>
And in a template for the note tags I'm trying to use the ancestor
axis to get the list [ para , content , article ].
However, I only seem to get [ para ] with ancestor::* and [ para , ""
] with ancestor::node().
When I test it like this:
<xsl:template match="note">
ancestors="<xsl:value-of select="count(ancestor::*)"/>"
preceding="<xsl:value-of select="count(preceding::*)"/>"
contentNum="<xsl:value-of select="count(preceding::content)"/>"
</xsl:template match>
...I get ancestors="1", preceding="2" and contentNum="0" as output.
What I actually need to do is to count the number of content nodes
preceding the current note (relevant for the input XML note numbering
scheme). I did so earlier in the document (for referencing the actual
notes) when matching document like this:
<xsl:template match="document">
(...)
<xsl:for-each select="//note">
<note>
<xsl:attribute name="id"><xsl:value-of
select="count(ancestor::content/preceding::content)"/></xsl:attribute>
<p><xsl:apply-templates/></p>
</note>
</xsl:for-each>
(...)
</xsl:template>
So here I get access to all of the notes ancestors. In retrospect I
could probably have used select="count(preceding::content)" instead,
but still...
How come that I cannot access the notes ancestors from my note template?

Jostein
