Re: Enumerating template matches

<xsl:template match="B">
 <xsl:apply-templates select="C">
   <xsl:with-param name="match_number" select="position()"/>
 </xsl:apply-templates>
</xsl:template>

<xsl:template match="C">
 <xsl:param name="match_number"/>
 <xsl:value-of select="$match_number"/>
</xsl:template>

This one did not work, only outputs 0's.

I think that's a bug: position() should never by zero. Which processor?

Mm.. Xalan-2.2.14. But wouldn't you suspect it to be the parameter
passing rather than position() as it works when I use call-template
rather than apply-templates?
