xslt 2

<xsl:function name="dp:childCount">
  <xsl:param name="nm" />
  <xsl:variable name="cnt">
  <xsl:sequence as="xs:integer">
  <xsl:for-each select="$root//*[name() = $nm]">
    <xsl:value-of select="count(.//*)"/>
  </xsl:for-each>
</xsl:sequence>
</xsl:variable>

<xsl:sequence select="avg($cnt)"/>
</xsl:function>


Failing miserably.
$root set to root of source document.
param is a string, name of an element in that document.

Requirement is to return the average number  of children over
all such elements in that document.

Idea is to build a sequence of ints, each being the count of
the number of element children.

Any help appreciated.
