position() and last()

Hello,
 
I am using cocoon 1.2. I can't use 'position()' or 'last()' in <xsl:if>
test. I tried this example of the xslt specification:

<xsl:template match="namelist/name">
  <xsl:apply-templates/>
  <xsl:if test="not(position()=last()))">, </xsl:if>
</xsl:template>

and a comma is written after the last name.

Does cocoon recognize 'position' and 'last()'?
Must I install cocoon 1.4?

I can't find tutorials about xsl. Everything I found was obsolete and
the xslt specification is sometimes hard to understand (specially for a
french). Do you know a good and recent tutorial?
I am looking for some web sites which use cocoon and some code examples
too.

Thank you,

Emmanuel Leguy
