Hi Wendell,
 The syntax <xsl:value-of
select="count(preceding::item[category=current()/category])+1"/>
when placed at <!-- ?? --> in my XSL, produces
numbering 1,2,1,2 and not 1,2,3,4 !

I am also interested to know how the numbering
(1,2,3,4 ..) can be produced using
- a 2 pass solution
- using node-set extension

Regards,
Mukul
